How do you make an object move?

There must be a force acted upon it great enough to move it

What is a Spring Scale?

a tool used to measure force

200

What do you call a push or a pull?

A force

You and your friend get a flat tire. You decide to push the car back to your house. The car requires 800N of force to move. You push 450N. How much does your friend have to push for the car to start moving?

At least 350N

What is friction?

A force acting between two forces that resists motion.

200

If two people are pushing on an object to the right at 6N each, how much force is being acted upon that object?

12N

200

What is a Newton?

the unit used to measure force

300

What is the metric unit used to measure force?

Newton (N)

What happens to Spring Scale A when you hold it still and push against it with Spring Scale B with 4N?

Spring Scale A will push back with 4N.

300

How does texture of a surface affect friction?

The smoother the surface, the less friction. The rougher the surface, the more friction.

If Sam is pushing on a cart to the right with 80N of force and Adam is pushing on the same cart to the left at 75N. Which direction is the cart moving and at what force?

To the right 5N

300

What is a Kinetic Energy?

the energy of an object in motion

400
If a book is on a table not moving, what forces are being acted upon it?

Gravity is pulling it down and the table is pushing it up with the same force.

400

If you and your partner are pulling a car in opposite directions with a spring scale using 5N of force, what is happening to the car?

The car is not moving.

You want to reorganize your bedroom that is carpetted. You need to push your dresser to the other side of the room. If the dresser requires 100N and the carpet is also pushing back on it with 75N, how much force do you need to get the dresser to move?

At least 175N

If Maddy is pushing on a box with 35N to the right and Olivia is pushing on the same box in the same direction with 40N, what direction is the box moving and at what force?

75N to the right

What is Potential Energy?

stored energy based on the object's position
500

What is Isaac Newton's Third Law?

For every action, there is an equal and opposite reaction.

500

What is Isaac Newton's First Law?

An object at rest, stays at rest unless acted on by a force. An object in motion, stays in motion unless acted upon by an unbalanced force.

500

What will happen if you walk into a room that has NO friction?

You will continue sliding around until a force is acted upon you.

During a football game, you are pushing against your opponent who is pushing you in the opposite direction. If your opponent is pushing you at 600N and you're pushing back at 601N, which one of you is moving and at what force? 

The opponent is moving at 1N.

What is gravity?

the force on Earth that pulls you down
