When does an object have no kinetic energy?
When it's at rest.
When it's moving very slowly.
When the only force that's acting on it is gravity.
When it has no electrical charge.
Which of the following is the correct equation for calculating an object's gravitational potential energy?

The spring constant of an object tells you?
What type of spring you are dealing with
How long the spring will stretch or compress
It gives you a value on how easy or hard it is to change the objects length.
A spring constant gives you a number which tells you what material the spring is made of.
What happens when two forces act in the same direction?
They cancel each other out.
The stronger one prevails.
Their strengths are added.
Their sum divided by two is the total force.
The force of gravity on a person or object on the surface of a planet is called
mass.
weight.
terminal velocity
free fall.
The momentum of an object is in the same direction as its
force.
velocity.
acceleration.
inertia.
The overall force on an object after all the forces are added together is called the
balanced force
unbalanced force
net force
centripetal force
