Application Task - We do
1

A car is travelling at a steady velocity of 7m/s to the right. Explain what happens to the car when the friction increases.

Application task - You do
1

A car is stationary. When the engine is turned on and the accelerator peddle pushed down there is a greater forwards force from the thrust of the engine. Explain what will happen to the motion of the car.
