​

force – a pull or push that acts on an object

mass – A measure of the amount of matter in an object. The mass of an object is related to the force required to accelerate it.

acceleration/force – the more force you apply, the greater the acceleration

acceleration/mass – the greater the mass, the more force necessary to get an object to accelerate

balanced forces – when all the forces on an object cancel each other out, you have balanced forces – no acceleration, no momentum

unbalanced forces – when forces don’t cancel each other out, there is movement. This is a result of unbalanced forces.

momentum – momentum measures how difficult it will be to stop an object

action – when one object applies a force to another object

reaction – the force the second thing returns (the result of an action)

inertia – then tendency of an object to resist a change in its state of motion

friction – a force that opposes the motion of one object moving past another

speed – how fast the position of an object changes with time at any moment

Newton’s First Law of Motion – “An object at rest tends to stay at rest; an object in motion tends to stay in motion.”

velocity – the speed of a moving object taken together with its direction of travel

acceleration – a change in velocity

acceleration – a change in velocity

deceleration – when a force causes the speed of an object to decrease
