100
a force can make these changes
What is start an object in motion, stop and object in motion, change its direction or speed
100
a force that stops or slows thing down
What is friction
100
motion is
What is a when an object changes positions

What is zero.
200
the ability to do work
What is energy

this causes a ball to fall to the ground
What is gravity
200
the energy of motion
What is kinetic energy
200
to put an object in motion, you have to
What is apply a force
200
Ms. Washington was snowboarding down a hill. She was halfway down the hill. Her potential energy has started to
What is change into kinetic energy
300
any push or pull
What is a force?
300
Ms. Lambert can sit in a chair and not fall on the ground because
What is she is pushing on the chair with the same force as the chair is pushing up on her.
300

300
Ms. Faye experimented with a marble roller coaster. She was disappointed that the marble stopped before it reached the end. Explain to her why the marble stopped.
What is friction slowed it down and forced it to stop.
300
To get the most momentum, you should
What is have the most mass and speed
400
the use of a force to move an object
What is work?
400
I push on my sister with 85N of force. She pushes back on me with 75 N of force. What happens?
What is I will keep pushing my sister and she will move back because I am pushing with more force than her.
400
this is what happens when object collide
What is transfer of energy
400
to get an object to increase its speed, you should...
What is apply more of a force
400
When a moving object collides with a stationery object...
What is the moving object transfers kinetic energy to the stationery object causing it to move
500
the tendency of an object to keep doing what it is doing- staying at rest or staying in motion
What is inertia?
500
Ms. Hannah's car broke down. she tried pushing the car, but it wouldn't move. Her daughter got out of the car and helped her. Together they will able to push the car to the side. Why wasn't Ms. Hannah able to move the car by herself?
What is the car has a lot of mass. This means you need more force to move it. Together, Ms. Hannah and her daughter had more force and were able to move the car.
500
the property of a moving object to keep moving
What is momentum
500
When an object stops moving, its momentum is
What is zero.
500
