1. What is the formula for momentum?
• M= Mass x velocity
• M=PV
2. State Newton's 2nd law.
• Unbalanced force acting on an object equals the object's Mass x Acceleration
• F=MA
3. State Newton's 3rd law.
Every action has an equal and opposite reaction.
4. State Newton's 1st law
An object at rest stays at rest and an object in motion stays in motion unless acted on by an opposing force.
5. SI Unit for Force?
Newtons
6. If two objects with different masses travel with different velocities and collide, what law allows you to be able to predict the motion of the objects after?
Law of Conservation of Momentum
7. What is the tendency of an object at rest to remain at rest or if moving to continue moving at a constant velocity.
Inertia.
8. What is the unbalanced force that stops a ball from rolling on the floor?
Friction
9. Give an example of an object with no momentum.
Anything that isnt moving.
