Mechanical energy
(a) energy is related to SPEED and MASS.
(a) force is a force that can decrease the speed of an object and its kinetic energy. It is produced when a body slides on a surface.
A body will have more kinetic energy the faster its speed and
the bigger its mass.
TRUE
FALSE
(a) energy is related to POSITION.
(a) is the force that holds us to the ground and attract us
to it when we are in the air.
The potential energy of an object will depend on its _____ and
the ______ where it is located.
mass - volume
density - height
mass - height
speed - position
The bigger the mass and the higher the height of an object,
the smaller the force of gravity.
