100
The force of this acts on a parachute to slow the ball as it falls.
What is air resistance?
100
A push or a pull that acts on an object.
What is force?
100
A moving car changes this compared with non-moving reference points.
What is position?
100
An example of this law is that a bowling pin is sitting still until a bowling ball hits it.
What is Newton's First Law?
100
When a car rolls down a ramp, you expect its speed to do this.
What is increase?
200
This is the formula for speed.
What is distance/time?
200
The change in the position of an object.
What is motion?
200
A unit of force.
What is a newton (N)?
200
An example of this law is that it is harder to move a full grocery cart than an empty cart.
What is Newton's Second Law?
200
As a car rolls down a ramp, it loses potential energy and gains this.
What is kinetic energy?
300
When you drop a ball, this force acts on the ball to make it fall.
What is gravity?
300
A property that describes how objects tend to resist changes in motion.
What is inertia?
300
The amount of matter in an object.
What is mass?
300
For every action force acting on an object, the objects will apply an equal and opposite reaction force.
What is Newton's 3rd Law?
300
This is the property that an object has due to its mass and velocity.
What is momentum?
400
Change of velocity. Speeding up, slowing down and changing direction are all examples.
What is acceleration?
400
The location of an object.
What is position?
400
The measure of an object's speed in a certain direction.
What is velocity?
400
An object at rest will not move until a net force acts on it. An object that is moving will keep moving at the same speed and in the same direction until a net force acts on it.
What is Newton's First Law?
400
A car at the top of the ramp has this.
What is potential energy?
500
A ball pushes on a table is this, and then the table pushes the ball is this.
What is action force and reaction force?
500
Resistance force caused when two surfaces touch or rub against each other.
What is friction?
500
Force that exists between any two objects that have mass, pulling them together.
What is gravity?
500
An object's acceleration depends on the amount of force acting on the object and on the object's mass. The object will accelerate in the same direction as the force that acted on it.
What is Newton's 2nd Law?
500
If balanced forces act on an object, the object does this.
What is stays in the same position?
