Free Fall Motion Graphs

The video tutorial explains the motion of a ball thrown vertically upward, reaching a height of two meters before returning to its original position. It highlights the constant acceleration due to gravity, approximately -9.81 m/s², and discusses the ball's position and velocity at different points in its trajectory. The tutorial also covers the interpretation of position versus time and velocity versus time graphs, emphasizing that the velocity at the peak is zero. The concept of uniformly accelerated motion is reinforced throughout.

What is the initial scenario described for the ball's motion?

• The ball is dropped from a height.

• The ball is thrown vertically upwards.

• The ball is thrown horizontally.

• The ball is rolling on the ground.

What is the approximate value of the acceleration due to gravity acting on the ball?

• 9.81 meters per second squared

• 19.62 meters per second squared

• -9.81 meters per second squared

• 0 meters per second squared

At what point in its path does the ball have zero velocity?

• Halfway up its path

• At the maximum height

• At the start of its motion

• When it hits the ground

What does the slope of the position versus time graph indicate at the top of the ball's path?

• The ball is moving downward

• The ball is moving at constant speed

• The ball is at rest

• The ball is accelerating

What type of motion is the ball undergoing?

• Uniform motion

• Uniformly accelerated motion

• Circular motion

• Random motion
