Task question In my task question I am going to study why does the velocity vary downstream? To carry out this investigation we will be going to Carding Mill valley; carding mill valley is located near the border of Wales‚ North West England in Shropshire. (This can be seen on image 1) (Image 1) (Image 1) This means we are collecting primary data which is mainly so we can get accurate and reliable set of results. In order to answer the task question

is stronger then the terminal velocity that is when the object is going at a small velocity. Terminal Velocity When there is equal force acting on an object when falling such as gravity and air resistance at that stage it is called constant speed or terminal velocity. When the object is dropped the force of gravity initially is 100% but as it falls the air resistance becomes stronger making the gravity weaker and at one stage there will be terminal velocity. In some cases due to the mass

1. Alice throws the ball to the +X direction with an initial velocity 10m/s. Time elapsed during the motion is 5s‚ calculate the height that object is thrown and Vy component of the velocity after it hits the ground. 2. John kicks the ball and ball does projectile motion with an angle of 53º to horizontal. Its initial velocity is 10 m/s‚ find the maximum height it can reach‚ horizontal displacement and total time required for this motion. (sin53º=0‚ 8 and cos53º=0‚ 6) 3. The boy drops

Graphical analysis of human motion‚ where displacement vs time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 18.75m‚ average velocity is 1.88m/s and instantaneous velocity is 3.76m/s.

Srivastava’s Srivastava’s MOTION IN ONE DIMENSION 1. A particle is projected vertically upwards with a velocity 20 m s1 from the top of the tower of height 100 m. Determine the time it takes to reach the ground. Answer: t 2 1 6 sec. A particle is dropped from the top of the tower of height h. At the same instant another particle is projected vertically upwards from the bottom of the tower with such a velocity that it will be able to just reach the top of the tower. When and at what height from ground

The time it takes for the ball to hit the ground depends on v0 ‚ g and h. 004 10.0 points The velocity of a projectile at launch has a horizontal component vh and a vertical component vv . When the projectile is at the highest point of its trajectory‚ identify the vertical and the horizontal components of its velocity and the vertical component of its acceleration.

the displacement y of the stone? | The stone‚ starting with zero velocity at the top of the building‚ is accelerated downward by gravity. | | Reasoning The upward direction is chosen as the positive direction. The initial velocity v0 of the stone is zero‚ because the stone is dropped from rest. The acceleration due to gravity is negative‚ since it points downward in the negative direction. Solution | 2). After 3.00 s of free-fall‚ what is the velocity v of the stone? Solution 1). A football game

Relative Velocity and Riverboat Problems On occasion objects move within a medium that is moving with respect to an observer. For example‚ an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example‚ a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this‚ the magnitude of the velocity of the moving object (whether it be a plane or a motorboat)
