100
A push or a pull no an object
What is force?
100
An object's tendancy to stay at rest or keep moving unless a force has acted on it.
What is inertia?
100
A wheel with a rope that you pull to lift loads.
What is a pulley?
100
The more mass an object has the more ~this~ it has.
What is momentum?
100
When an object has no force acting on it it is in ~this~.
What is freefall?
200
A force with a net force of zero.
What is a balanced force?
200
The measurement of distance over time and direction.
What is velocity?
200
A simple machine with at least one slanted side.
What is a wedge?
200
An example of ~this~ is rubbing your hands together and feeling the heat.
What is friction?
200
The harder you kick a ball the more ~this~ is acting on it.
What is force?
300
A force with a net force that is not zero, causing movement.
What is an unbalanced force?
300
Distance over time.
What is speed?
300
A flat surface that lies at an angle.
What is an inclined plane?
300
The less mass an object has the less ~this~ an object has.
What is momentum?
300
A bar that makes it easier for people to move things and it includes an lever arm and a fulcrum.
What is lever?
400
The pull towards the center of the earth.
What is Gravity?
400
A change in velocity.
What is acceleration?
400
An inclined plane wrapped around a pole.
What is a screw?
400
~this~ is a force that slows an object down when it is in movement by rubbing against it.
What is friction?
400
The point of support on a lever (that never moves)
What is a fulcrum?
500
The total force acting on an object.
What is Net force?
500
Slowing down.
What is decelaration?
500
Machines that make working easier.
What is a simple machine?
500
~this~ is the thing that makes it harder for an object to stop movement.
What is momentum?
500
