Vertical motion under gravity

Book Falling From a Shelf

When an object falls freely to earth, assuming there is no air resistance, it accelerates at a constant rate of approximately 9.8 ms-2. In the next few examples I look at the motion of a particle falling freely under gravity. I start with a book falling from a shelf.

Stone Thrown Upwards from the Ground

When an object falls freely to earth, assuming there is no air resistance, it accelerates at a constant rate of approximately 9.8 ms-2. Here I look at a stone being thrown upwards from the ground.

Note: At 4:48 in the video I discuss the important point about the acceleration due to gravity, what sign to take and common misconceptions at 5:08.

Ball Thrown Upwards from a Balcony

When an object falls freely to earth, assuming there is no air resistance, it accelerates at a constant rate of approximately 9.8 ms-2. In this video I show you how to handle a particle being thrown upwards from above ground level.
