distance
the amount that you have travelled in total
displacement
the measure of how far way a object is from its starting point
distance and displacement word problems
state positive and negative and directions
steepness of slope means
speed of an object
average speed
rate of an object
velocity
describes the rate and direction of an object
large distance between distance (ticker tape)
moving fast
small distance between distance (ticker tape)
moving slow
the greater the force
the greater the acerlation
energy
ability to do work
work
force applied over a distance
in order for work
- the object must move
- the force must be in the same direction as the motion
chemical energy
potential energy stored in chemical bounds
electrical energy
electrical charge moving (current)
nuclear energy
potential energy from nucleus of an atom
solar energy
nuclear energy to radiant energy
kinetic energy
energy from motion of an object
gravitational potential energy
energy from the position of an object above a surface
elastic potential energy
energy from change of shape of elastic object
chemical potential energy
energy stored when there is build of charge
mechanical energy
sum of both kinetic and potential energy
potential energy to kinetic
speed increase (ball falling down-gains speed)
