Terms in this set (24)
A push or pull on an object
The SI unit to measure force
Net force equals zero, no movement
Net force not equal to zero, movement
When a force causes a change in motion or position of an object.
W = f x d
SI unit of work and energy
Rate at which work is done
P = W / t
SI unit of power
the ability to do work
Gravitational Potential Energy
Energy stored in an object due to its vertical position or height
Gravitational Potential Energy equation
GPE = m x g x h
Energy of motion
Kinetic Energy Equation
KE = 1/2 x m x v2
Conservation of Energy
Energy cannot be created or destroyed
The sum of potential and kinetic energy; energy of objects in motion
The value of gravity.
Unbalanced force that acts against the direction of motion
non-moving friction. Resists the start of motion.
moving friction. Will be felt when objects roll, slide or move through a fluid.
total forces acting on an object
A force that causes an object to move in a circle
Elastic potential energy
the energy of stretched or compressed objects, like rubber bands or springs
