Keep in mind that you can utilize the two main concepts of a speed-time graph. As object is under free-fall, the acceleration (the...

1) When a ball is thrown up and it comes down When the ball leaves the hand, there is no upward force acting on the ball. The only force...

When a ball is thrown up vertically from a height and the falls to the ground, the various kinematic graphs below shows the same motion...

Think of gradient as the steepness of a slope as you climb to the right (as time increases). 1) If it is getting steeper > increasing...

The distance-time (displacement-time) graph on the left is not related to the speed-time (velocity-time) graph. Both are of difference...

On earth, the gravitational field strength is 10 N/kg and the acceleration due to gravity is 10 ms-2 . That means when you release an...

The speed-time graph of Car A and Car B, along a straight road over 4 seconds is shown below. a) Calculate the acceleration of Car A and...

A 10 kg box is initially at rest on a rough horizontal surface and a horizontal force is then applied to it. The force varies as shown in...

A rock is thrown vertically upwards with a velocity of 29.4 m/s from the top of a building 78.4 m high. After how long will the rock...

Solutions: Option B Key concepts: Both balls are free-falling, hence both will experience the same acceleration due to gravity 10 m/s2.
