What force is needed to accelerate a car of mass 1000kg at a rate of 6m/s2?
What is the acceleration of a 10kg mass when a force of 500N acts on it?
As a space shuttle uses up fuel, its acceleration increases because:
Its thruster force increases
Its mass increases
Its mass decreases
When a car is stopping the thinking distance can be increased by:
When driving a car, the braking distance is increased by:
