1. What is meant by net force? Draw a diagram as part of your answer.
2. Suppose a cart is being moved by a certain net force. If the net force is doubled, by how much does the cart’s acceleration change?
3. How much force does a 20,000 Kg rocket need to have an acceleration of 1 m/s2?
4. If a 1N net force accelerates a 1 kg mass at 1 m/s2, what is the acceleration caused by a net force of 2 N on a 2 kg mass?
5. A certain force applied to a 2 kg mass accelerates the mass at 3 m/s2. How much acceleration will the same force make on a 4 kg mass?
