Additional Questions: [Answer underneath Questions 18-23 from the book]

1. Define: “centripetal force”and “uniform circular motion”
2. Explain why the book states, on page 147, that “even though it is given its own name, centripetal force is not a new force”.
3. You are spinning a ball on a string. You release it. Explain what will happen to the ball immediately after its release, according to Newton’s First Law. 
4. Explain why high speed turns must have a large radius. 

1. State Newton's First Law IN ITS ENTIRETY.
2. Draw free body diagrams (See Free Body Diagram WS1)
3. Determine whether an object is experiencing balanced or unbalanced forces from a FBD
4. Determine the net force on an object (the strength AND the direction) using a FBD
5. Explain how the presence (or lack there of) of a net force will affect the motion of an object (See "Practice Sheet": Balanced/Unbalanced Forces)
6. Explain how an object's acceleration is affected if the force or the mass is changed. 
7. Utilize Newton's 2nd Law (Fnet = m x a) to calculate an object's acceleration. 
8. Differentiate between weight and mass. 
9. Use free body diagrams to solve for missing variables (See FBD's and Newton's 2nd Law WS1 and WS2)

Explain independent motion in 2D

Define: range, trajectory, projectile, and apogee

Define givens as being either horizontal or vertical. 

Place appropriate S.I. units on all givens and answers.

Explain whether or not there is acceleration in the horizontal direction and in the vertical direction. 

Fill in a diagram with the horizontal and vertical velocities over time. 

Utilize your three equations to calculate the time in the air for any projectile motion, the horizontal and vertical distances traveled, and the final vertical velocity.
