Potential Energy
When is potential energy greatest in a roller coaster?
At the top/beginning
When is kinetic energy greatest in a roller coaster
At the bottom when the roller coaster is already in motion
What is a electric force?
A force between charged particals
What is a force?
Something that pushes or pulls
what is newtons third law?
for every action there is an equal and opposite reaction.
When a roller coaster is going down is the potential energy greatest?
no
When a roller coaster is going Down is the kinetic energy greatest?
no
What is attract?
When two objects pull towards one another
What is motion?
The change in an objects position with respect to time and in comparison to the position of other objects used as reference points.
What is newtons second law of motion?
the acceleration of an object is directly related to the net force and inversely related to its mass
