Topic 1: Force & Motion

Using what you know about F=ma, which ball would have the greater force if traveling at the same acceleration? Tennis ball=1 ounce and the baseball=5 ounces

• 
• 

What is the net force?

• 10 N
• 0 N
• 25 N
• 1 N

If you want to increase the acceleration of a baseball when you throw it, what must you increase to make this happen?

• Force

• Acceleration

• Mass

• Newton's 2nd Law

You have two objects of the same mass that collide. If they are going the same speed when they collide. What would be the result of the force?

• The net force is going towards the left.

• The net force is going towards the right.

• The net force is zero. The forces will cancel each other.

What unit do scientists use to measure force?

• Newton

• Grams

• Meters

• Meter per second per second

What is the net force on the box shown in the picture?

• 10 N to the left

• 10 N to the right

• 60 N to the left

• 50 N to the right

A change to an object's motion is caused by . . .

• Balanced forces

• Unbalanced forces

• Acceleration

• Velocity

A push or pull exerted on an object

• time
• force
• motion
• thrust

The state in which one object's distance from another is changing

• time
• force
• meters
• motion

This graph shows the distance traveled by a remote control toy car over time.

If the car continues moving at the same rate, how far will it travel in 2 minutes?

• 10 m

• 60 m

• 120 m

• 200 m
