200
this is accomplished when force is applied to an object
What is work?
300
2 or more simple machines working together.
What is a compound maachine?
300
speed + direction
What is velocity?
300
An object at rest stays at rest while an object in motion stays in motion.
What is the first law?
300
if it is bigger or going faster it has... this.

What is fixed pulley, moveable pulley, and block and tackle?
400
formula for velocity
What is V=d/t?
400
Whenever one objects exerts a force on a second object, the first exerts an equal and opposite force on the first
What is the third law?
400
the one with greater momentum between a train at rest or a train moving
What is the train moving?
400
amount of work done if you push a box with 30 newtons of force and it goes 2 meters.
What is 60 joules?
500
the three types of levers.
What is first class, second class, and third class levers?
500
speed if going 120 miles in 2 hours
What is 60 miles per hour?
500
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is the second law?
500
you change this if the object is moving at a constant velocity and you want to change the momentum
What is mass?
500
the amount of force used if you push a 36 inch box with the force of 40 newtons and you push it 5 meters.
What is 200 joules?
