3.1-3.4 Force and Motion Review

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

_______________ is how fast an object changes over time. 

• speed
• velocity
• momentum
• acceleration

What is the formula for force?

• F=M/A
• F=A/M
• F=M*A
• F=M*F

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

• motion
• velocity
• acceleration
• mass

What is the net force on the block? (click on the words to view the picture)

• 5 Newtons up
• 5 Newtons down
• 15 Newtons up
• 15 Newtons down

What does this graph represent?

• Constant speed
• Acceleration
• Not moving

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

• 150 Newtons
• 15 Newtons
• 150 kilograms
• 100 kilograms

Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

Speed is different from velocity because

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