Physics Review sheet

Unit 1 - Kinematics

1. Be able to use and rearrange the following formula
d = ½ (vi + vf) t vf = vi + at d = vi t + ½ at2 vf2 = vi2 + 2ad
a = (vf - vi) ÷t d = v t

2. Know and interpret distance-time graphs, velocity-time graphs, and acceleration-time graphs

3. Know the difference between each scalar quantities and each vector quantities

4. Be able to make a graph, draw the line of best fit, and calculate the slope of it

Unit 2 - Dynamics

5. Be able to calculate weight (Fg = m g) and the equal and opposite normal force (FN )

6. Understand Newton’s 3 Laws, be able to use the formula Fnet = m a , and understand that inertia is an object’s tendency to continue in its current motion (think of it as the object’s mass)

7. Understand the forces acting on an object so you can draw FBDs (Free Body Diagrams) of the external forces acting on that object

8. Be able to calculate the friction force (Ff = μ FN ) and understand the difference between static friction (still) and kinetic friction (moving)

9. Be able to calculate your weight on other planets when given their gravity
