“How does Motion and Forces help your everyday life?”

All your life, forces has been acting on you even though you probably didn’t notice it. When you use your pencil, type, walk, or even when your doing something your using force. Those were a few examples of everyday life because, that’s what a force is “everyday life”. Everyday you use force to make your life easier.

The correct definition of “Force” is a push or a pull. I’ve always remembered that. For an example, when your doing homework you use a force on your pen or pencil because you push and pull it across the paper. Sometime two forces act on something at the same time, that’s called net force. If two people were pushing a shopping cart and they were pushing in the same direction, you would add the two forces together.

Net force is an unbalanced force, an unbalanced force is a force that changes the object’s motion or causes it to accelerate. Something else can happen if two forces move in one direction. If one force is more powerful then the other, they will not balance out to zero net force because , one force is stronger than the other, so the weak force is not strong enough to completely balance out the stronger force.

In the examples I mentioned earlier suppose there is a person in the front of a shopping cart and one on the other end, they are pushing with a much greater force. Since the forces are not balanced, the shopping cart is moving in the direction that the person with the stronger force is pushing. Once you think about everyday life, and you think about “Motion and Force” you’ll see and realize it does makes life easier.

Thinking of examples of force is very easy once you get the hang of it. Sports have a lot to do with force, and so does moving things around the house. Force is everywhere. Say if a girl is playing tennis and she exerts a force on the ball with her racket causing it to accelerate. That...

...Force & Motion
Isaac Newton – English physicist & mathematician.
Newton’s First Law of Motion(Law of Inertia):
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalance force.
An object at rest tends to remain at rest. An object in motion tends to move at a constant speed in a straight line unless acted upon by an unbalanced external force.
Newton’s Second Law of Motion(Law of Acceleration):
An object’s acceleration is directly proportional to the net force acting on it and is inversely proportional to the object’s mass.
Newton’s Third Law of Motion(Law of Interaction):
For every action, there is always an equal and opposite reaction.
Force is any interaction which tends to change the motion of an object. It can also be described by intuitive concepts such as a push or pull.
Unbalanced Forces
An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
Direct proportion- means that when one factor increases, the other factor also increases and vice versa.
Inverse proportion- means that when one factor...

Forces are also described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate.

In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or a flexible object to deform, or both. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.
The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.[1] If...

ABSTRACT
I thought it would be fun to fling things like raw eggs and rocks with a catapult. Guess
what, it was! By flinging these items I tried to find out if heavier things would travel farther than
lighter ones. Basically how force effects motion.
With the catapult as the force, I sent items soaring, after weighing them, and then
recorded how far the items travelled. This showed me how Newtons Three Laws of Motion
work.
Force causes change is Newton's First Law of Motion which I saw from the catapult
flinging the items.
My hypothesis that heavier items would go farther was not correct, because Newton's
Second Law of Motion says that the force applied is equal to mass times acceleration. For
instance, if you push a skateboard it will roll away, but if you push a car with the same amount
of force, it will barely move. So heavier items do not travel farther.
Newton's Third Law of Motion is that for every action there is an...

...FORCE AND MOTION
Scalars vs. Vectors
Scalars | Vectors |
A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. |
Scalars can be added, subtracted, multiplied and divided just as ordinary numbers, i.e., scalars are subjected to simple arithmetic operations. | Vectors cannot be added, subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. |
Example: mass, volume, time, distance, speed, work, temperature | Example: displacement, velocity, acceleration, force |
Distance and displacement
Distance is defined as the ground covered by a moving object during its motion. Its SI unit is metre (m). It has only magnitude, but no direction. Distance can never be negative. The minimum value of distance is zero.
Displacement is defined as how far an object has moved relative to the starting point. Its SI unit is metre (m). It has both magnitude and direction. Displacement can be positive, negative, or zero.
Speed and Velocity
Speed is a physical quantity that enables us to know how the position of an object changes with time, i.e. speed gives us an idea about the slowness and fastness of a moving object. It is obtained by dividing the distance travelled by a body by the total time taken to cover that distance.
speed =
i.e.,
where, s = speed of the moving object
d= distance travelled by the object
t = time taken to...

...„throwing“/“putting“(throwing in a pushing motion) a heavy spherical object (the shot) as far as possible.1 The shot put has ancient origins in strong man competitions, in which stones were originally thrown instead of metal balls.
We have found that force of gravity, and acceleration play a role to a flying object. Force of gravity affects the object vertically while force of acceleration may differ between how the object is being thrown. In fact, it will always change unlike force of gravity. These forces affect everything we do, from walking to class to passing a pencil to a friend. In relation to everyday life, there is a clear connection to many kinds of sports. Projectile motion can be applied to any object due to the forces the athletes apply on it. By knowing these forces, it gives the athlete an advantage to know where the object might be later on. For example, from a athlete’s perspective, acquiring experience from becoming more intuitive with an objects motion will aid him or her in knowing how far the object might travel. The athlete will know how much force to apply on the object to score a goal. Of course the athlete cannot calculate the exact amount of force during a game so the athlete will have to use instinct and previous experience to estimate how much force to apply to...
