Physics Chapter 4 Review

What does an unbalanced force produce?

Which equation do you use to solve for the Normal Force on Q11 SG? Choose the MOST CORRECT

If you see appears to weigh/ scale reads, what should you solve?

Which object experiences the greater force?

Used to solve for questions that ask how far, how fast and how long for an object at constant v

Read: Q5B on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Equals the force needed to start an object's motion

What do we use to solve for acceleration?

equals the normal force (for an object on a ramp)

Read: Q4 on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Type of friction is used when trying to stop a car in the shortest distance/ time possible

Read: Q2A on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Read: Q7 on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Friction car experiences during a skid

Read: Q12 on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

perpendicular component of gravity (for an object on a ramp)

Unit:N

AKA: the force of gravity acting on an object

parallel component of gravity (for an object on a ramp)

Equals the force needed to keep an object moving at a constant velocity

Unit: kg

Can an object in equilibrium be in motion?

For every action force there is an equal and opposite reaction force

This type of friction for objects at rest

This type of friction is always larger

This type of friction for objects moving

Used to solve for questions that ask how far, how fast and how long for an accelerating object

Read: Q1E on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Read: Q1D on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

Read: Q9A on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

A box sits on a ramp at rest. How many forces are acting on it?

When do objects appear to weigh more or less?

Friction for car that is not skidding

ALWAYS acts down a ramp

Pick the MOST CORRECT: What 2 objects are involved for the action-reaction forces for the image

Net Force = mass x acceleration

Object@rest stays@rest, object moving stays moving unless acted upon by outside net force

Read: Q9B on Study Guide. Choose the MOST CORRECT equation you would use to solve the problem.

This is always the same anywhere in the universe
