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
