Motion & Forces Review

A push or pull that can change the position and/or motion of an object

• Friction

• Force

• Gravity

• Magnetism

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

When you tell the direction and speed of an object, you give its

• motion
• velocity
• acceleration
• mass

Which of the following objects has the least acceleration?

• a. an empty shopping cart pushed with a hard force
• b. a full shopping cart pushed with a hard force
• c. an empty shopping cart pushed with a light force
• d. a full shopping cart pushed with a light force

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

A object with a lot of mass needs more force or less force to be moved? 

• More
• Less

Quickness of motion

• speed

• gravity

• velocity

• center

A change in velocity over time

• gravity

• acceleration

• friction

• motion

The tendency of an object in motion to stay in motion and an object at rest to stay at rest

• roller coaster

• force

• inertia

• acceleration

A change in an object's position

• velocity

• friction

• inertia

• motion
