Movement and Position

State the SI unit for acceleration.

Give one example of a vector quantity and one example of a scalar quantity from motion.

A sprinter starts a race at 0 m/s and reaches a speed of 10 m/s in 5 s. Calculate the sprinter's acceleration.

An athlete runs around a circular track at constant speed. Explain why the athlete’s velocity is not constant.

A car’s velocity changes from +15 m/s to -5 m/s in 10 seconds. What does the negative sign mean in this context? State your answer clearly.

Write the equation linking acceleration, initial velocity, final velocity, and time.

State what the vertical axis represents in a velocity–time graph.

On a velocity–time graph, what does it mean if the line is horizontal?

A car’s velocity–time graph shows a horizontal line at 15 m/s between t = 0 s and t = 8 s. How far does the car travel during this interval?

Calculate the acceleration of the object from the table above.
