(38 cards)
Inertia
Resistance to change in motion
Motion
Your change in position to another object
Force
Push or pull against an object
Newton
Unit of measurement when talking about weight
Friction
When two object rub against eachother
Gravity
An invisable force pulling objects down
Velocity
A speed at which an object travels and a a given direction
Acceleration
A rate at which velocity changes
Collision
Two objects colide
Mass
Amount of matter in an object measured in kg or grams DOES NOT CHANGE
Weight
Force of gravity on an object
Equation for gravity
Gravity = 9.81 m/s 2
Velocity equation
Distance divided by time
Force equation
Mass xacceleration
Kinetic energy equation
1/2 mass times velocity

Slope straight line
Constant speed
Slope line curved
Changing speed
Relative motion
How an object appears in pov of another object
What’s the law of conservation
Energy cannot be created or destroyed
Transferred energy def.
When one type of energy is transferred around and does not change
