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.,[object Object]
acceleration/force – the more force you apply, the greater the acceleration,[object Object],Click on the picture for some great questions about acceleration and force!,[object Object]
acceleration/mass – the greater the mass, the more force necessary to get an object to accelerate,[object Object],Click on the picture!,[object Object]
balanced forces – when all the forces on an  object cancel each other out, you have balanced forces – no acceleration, no momentum,[object Object],Click on the picture for some great questions about balanced and unbalanced forces.,[object Object]
unbalanced forces – when forces don’t cancel each other out, there is movement.  This is a result of unbalanced forces. ,[object Object],Click on the picture for some information about unbalanced forces.,[object Object],Click on the picture for some information about kinds of forces.,[object Object]
momentum – momentum measures how difficult it will be to stop an object,[object Object],Click on the picture for some information about momentum.,[object Object]
Newton’s First Law of Motion – “An object at rest tends to stay at rest; an object in motion tends to stay in motion.”,[object Object]
velocity – the speed of a moving object taken together with its direction of travel,[object Object]
acceleration – a change in velocity,[object Object]
acceleration – a change in velocity,[object Object]
deceleration – when a force causes the speed of an object to decrease,[object Object]
incline – a ramp/slope ,[object Object]
pendulum – something hanging from a fixed point that swings due to gravity and then out due to inertia ,[object Object],Click on the picture below to check out a link on pendulums,[object Object]
gravity – something hanging from a fixed point that swings due to gravity and then out due to inertia ,[object Object],Click on the picture below to check out a link on gravity.,[object Object]
