Forces and Motion Study Guide Students will need to know the following: 1. Definition for Newton’s 1st, 2nd, and 3rd Laws of Motion 2. Inertia is a resistance to change in motion 3. Formulas S= D/T Speed = Distance/ Time ; Momentum= mv; a= Vf - Vi / t (acceleration) 4. Unit for momentum: kg-m/s 5. Potential Energy: stored energy – energy due to position Kinetic Energy: energy of motion 6. Mass: amount of material in an object Weight: gravitational pull on an object 7. Acceleration: A change in either the speed of an object or its direction of travel 8. Momentum: The product of an object’s mass and velocity 9. Two factors that make up velocity: speed and direction 10. Velocity: how fast an object is going in a given direction 11. The causes for a large momentum: greater mass and high velocity 12. Force: a push or pull that causes a change in motion 13. N= Newtons or kg-m/s2 ( Unit for Force) 14. Friction: Force that acts between two objects in contact 15. Pressure: P= F/A Unit psi 16. Remember that mass is a measure of an object’s inertia. More mass= more inertia 17. Read over the different pressure experiments. Have a basic understanding of them
