What is force?
100
force that acts in an opposite direction slowing an object down evenutally causing it to stop.
What is friction?
100
1665- 1666
What years were laws of motion founded?
100
force of attraction that depends on the mass of two objects and the distance between them; responsible for accelerating an object toward the earth.
What is gravity?
100
property of matter that tends to resist any change in motion
What is inertia
200
A force gives energy to an object, sometimes causing it to start moving, stop moving, or change direction.
What is does force do?
200
Rolling and sliding?
What are 2 types of friction?
200
Issac Newton
Who founded the laws of motion?
200
9.8 m/sec
At what rate do all objects fall
200
unit of force 1kg x 1m/sec/sec
What is newton
300
Force= Mass x Acceleration
how do you find force?
300
It causes friction between you and the ground.
Why does having a grip help you on a wet substance?
300
An object at rest stays at rest until an outside force acts upon it. An object in motion will stay in motion until an outside force acts upon it.
What does the first law of motion state?
300
That two objects of a different weight the lighter one can land first.
What did Galileo find?
300
law that states that energy is neither created nor destroyed by the force of gravity.
What is law of universal gravitation
400
All force is going one way.
What is an unbalanced force?
400
It changes how motion accelerates or move period.
How does friction affect motion?
400
shows how force, mass, and acceleration are related
What does the 2nd law show?
400
Weight.
What does gravity depend on? weight or mass?
400
description of speed in a given direction
What is velocity
500
2 opposing forces going against each other.
What is a balanced force?
500
No.
Does friction always help?
500
For every action there is an equal or opposite reaction.
What does the 3rd law of motion state?
500
Pulls us toward the earth.

500
rate of change in velocity
What is acceleration
