• Force that resists the motion of objects or surfaces

Friction force that resists motion between 2 surfaces that are not moving

every action force creates a reaction force that is equal in strength and opposite in direction

the rate of change of velocity

force causes acceleration and mass resists acceleration

an object at rest will stay at rest and an object in motion will stay in motion with the same velocity unless acted on by an unbalanced force

a net force on an object that can cause changes in motion

the amount of matter an object contains

the downward force of gravity acting on mass

friction force that resists motion of an object moving across a surface

the distance divided by the total time for a trip

speed with direction

the speed of an object that travels the same distance each second

the amount of matter an object contains

result in a zero net force

sum of 2 or more forces on an objest

the force of gravity between objects depends on their masses and the distance between them

the property of an object that resists changes in its motion

a push or pull,or any action that is able to change motion

the distance an object travels divided by the time it takes
