100

A field force which causes objects to accelerate toward the ground

What is gravitational force?

100
An object at rest remains at rest, an object in motion will remain in motion at a constant speed and in a straight line unless by an unbalanced force.
What is NewtonĊ› First Law of Motion?
100

A Newton

What is the unit of force?

100
p=m x v
What is the equation for momentum?
100

meters per second (m/s)

What is the units of velocity?

200
The tendency to resist a change in motion.
What is inertia?
200
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is Newton's Second Law of Motion?
200

A push or pull on an object.

What is a force?

200
Mass and velocity.
What is the two things that momentum relies on?
200

meters or kilometers

What is the units of displacement?

300

A measure of the motional inertia an object has

What is momentum?

300
The length of time that a force is applied on an object

What is Impulse?

300

What a net force causes.

What is acceleration?

300

This can occur when an object goes from positive momentum to negative momentum

What is rebound?

300

meters per second per second (m/s2).

What are the units for acceleration?

400

The rate of change of velocity a moving object has.

What is acceleration?

400

F x t = change in momentum

What is the Impulse-Momentum Theorem?

400

Changing momentum from 10 kg-m/s to 15 kg-m/s

What is an impulse of 5 N-s?

400
The Law that momentum can relate to.
What is the Newton's Third Law?
400

kilograms-meters/second (kg-m/s).

What are the units for momentum?

500

When the graph of an object's position (displacement) versus time is a straight line.

What is constant velocity?

500

Softness, and bringing a catch into your body, use the concept that if you increase the time of stopping an object, this will decrease.

What is the force of impact?

500

A 3 kg mass, accelerating at 4 m/s2

What is 12 N?

500
Doesn't have a lot of momentum.
What is small car
500

kilogram-meters per second per second (kg-m/s2)

What are Newtons (the unit of force)?
