Title:
Do heavier objects fall faster than light objects?
Aim:
To observe whether a heavier or lighter object would fall first.
Background Information:
Gravitation or gravity is a natural phenomenon by which all physical bodies attract each other. It is more commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. The larger an object is, the greater the force of attraction will be. It was Italian scientist Galileo Galilei who formulated the laws of accelerated motion and free-falling objects. He found out that when an object is dropped and falls to the ground it has a falling rate of 9.8 meters per second, squared.
Newton’s law of universal gravitation states that any two objects in the Universe exerts gravitational attraction on each other, with the force having a universal form:
,
F=the gravitational force
G= the universal gravitational constant
R=Separation between the objects
M1= First Mass
M2=Second Mass
Hypothesis:
When two objects are dropped from the same height and distance at the same time, both objects would reach the ground at the same time
Two different objects (weight wise)
Measuring tape
Coins:
Stopwatch
Three 5cent coins
Wall
Three 20cent coins
Three 50cent coins
Glue
Equipment:
Risk Assessment:
Risk #1: The risk in this experiment is accidently dropping the objects onto your feet.
Injury: If the objects fall onto your feet you could end up with bruises from the heavier objects or even worse if the object is sharp it could stab you in the feet causing blood to rush out.
Precaution or Prevention: To prevent this from happening it is really important that you wear covered shoes to protect your feet from anything that May accidently fall onto your feet.
Risk #2: Another risk could be dropping the coin and actually damaging the floor
Injury: There might not be any injury but you floor might be damaged and in need of some
