Unit 5 Review

The distance an object travels in some amount of time is called

• Acceleration

• Force

• Speed

• Power

Speed in a specific direction is called

• Friction

• Gravity

• Acceleration

• Velocity

The rate at which speed changes is called

• Acceleration

• Force

• Velocity

• Friction

Jack runs 42 meters in 3 seconds. What is her speed? S = D/T

• 45 m/s

• 14 m/s

• 126 m/s

• 39 m/s

All the following are examples of acceleration except

• Changing directions

• Speeding up

• Moving in a straight line at a constant speed

• Slowing down

A plane flew 2000 kilometers from Virginia to California in 5 hours. What is the velocity?

• 400 km/hr

• 10,000 km/hr West

• 10,000 km/hr

• 400 km/hr West

Newton's 2nd Law of motion states that force is equal to

• length X width X height

• an opposite but equal force

• mass x acceleration

• mass divide by the volume

The formula for calculating work is

• force x distance

• mass divided by the volume

• input force - output force

• length x width

"An object at rest tends to remain at rest unless acted on by an unbalanced force"

• Newton's 2nd Law

• Newton's 4th Law

• Newton's 1st Law

• Newton's 3rd Law

What is another name for Newton's 1st Law of Motion?

• Law of Inertia

• Law of Action and Reaction

• Law of Acceleration

• Law of Gravity
