Balanced Forces
Object is not moving
Unbalanced forces
Object is moving
Newtons first law of motion
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a external force
Newtons second law of motion
The acceleration of an object is directly related to the net force and inversely related to its mass
Newtons Third law of motion
for every action there is an equal and opposite reaction
Kinetic energy
a form of energy that an object or a particle has by reason of its motion
Gravitational potential energy
the energy an object has due to its position above Earth, energy due to its height.
Elastic potential energy
The energy stored in something when you push, pull, or force it out of shape
Chemical energy
Energy stored in the bonds of chemical compounds, like atoms and molecules
Transverse wave
Transverse waves cause the medium to move perpendicular to the direction of the wave.
Longitudinal wave
Longitudinal waves cause the medium to move parallel to the direction of the wave.
Conservation of energy
a principle stating that energy cannot be created or destroyed, but can be altered from one form to another
Net force
Sum of all forces acting upon an object
