|
velocity
|
the rate of change of displacement; includes both speed and direction
|
|
|
average speed
|
equals distance divided by time
|
|
|
displacement
|
measures the change in position of an object, using the starting point and ending point and noting the direction
|
|
|
kinetic energy
|
energy an object has due to its motion; depends on the object's mass and velocity
|
|
|
speed
|
the rate of change of an object's position
|
|
|
average velocity
|
equals displacement divided by time
|
|
|
relative motion
|
motion of an object which is described relative to a particular frame of reference
|
|
|
law of conservation of energy
|
states that energy cannot be destroyed or created; it is only transformed from one form to another
|
|
|
inertia
|
measures an object's tendency to remain at rest or to stay in constant motion
|
|
|
GPE
|
equals force of gravity X height
GPE = mgh |
|
|
acceleration
|
the rate of change of velocity; can act in the direction of motion, at an angle, or opposite to the direction of motion.
|
|
|
gravitational potential energy
|
the energy an object could potentially gain if it falls, depending on its mass and the height it can fall
|
|
|
average acceleration
|
equals change in velocity divided by time
|
|
|
energy
|
the ability to cause change; cannot be destroyed or created, only transferred from one form to another
|
|
|
mass
|
quantity of matter in an object and a measure of the object's inertia; unit is the kilogram
|
|
|
momentum
|
mass X velocity
p = mv |
|
|
law of conservation of momentum
|
states that if no outside forces act on a group of objects, the momentum of the group will not change
|
|
|
momentum
|
the product of mass and velocity; quantity of motion for an object
|
