is the ability to do work or heat objects
energy
2 main energies
Kinetic Energy
Potential Energy
energy of motion
kinetic energy
stored energy
potential energy
the act or process of moving
motion
a resistance of motion
friction
described the rate of motion in an object
a scalar quantity
ex. V = 100km/hr
speed
is one that only indicates “how much” (the magnitude) of the quantity.
Scalar Quantity
indicates the “how much”(the magnitude)
Vector Quantity
is a change in velocity. an object accelerates if it speeds up, slows down or changes the direction it is moving.
acceleration
this means the acceleration is not changing
uniform acceleration
