What is stored energy?
potential energy
This is the energy related to motion.
This is the energy that an object has because of its position or condition rather than its motion.
kinetic energy
What is an example of stored energy? (Choose all that apply.)
charged battery
rolling ball
coiled spring
elevated weight
What is weight?
how long or tall something is
the amount of matter an object contains
It is the same as mass.
the force gravity applies to an object
What is the main difference between mass and weight?
There is no difference.
Weight is a force, and mass is not.
Mass is a force, and weight is not.
Mass has to do with the size of an object, and weight does not.
What is mass?
how much something weighs
how tightly packed an object is
the force gravity applies to an object
the amount of matter an object contains
What is height?
the measurement from head to foot
the measurement from base to top
the force gravity applies to an object
how tightly packed an object is
What is gravity?
the force which tries to pull two objects toward each other
the weight of an object
the mass of an object
the speed of an object
What is gravitational energy?
It is a type of potential energy.
It is a type of kinetic energy.
It is the energy held by an object because of its high position compared to a lower position.
It is an energy associated with gravity.
What is force?
movement of an object
push or pull upon an object because of an object's interaction with another object
a push but not a pull upon an object
only exist because of an interaction
What is velocity?
It is the same thing as speed.
the rate at which an object changes its position
It is the distance divided by time in a specific direction.
It is the distance multiplied by time in a specific direction.
Choose the correct facts about friction.
Friction happens when two objects are rubbed together.
Friction is the resistance that one surface or object encounters when moving over another.
Friction causes thermal energy.
Friction does not slow objects down.
Choose the correct facts about mechanical energy.
Mechanical energy allows one object to apply a force to another object and make it move.
Mechanical energy is the movement of electrical charges.
Mechanical energy can be kinetic or potential.
Mechanical energy is the energy one object has due to its motion.
Choose the incorrect statement about the Law of Conservation of Energy.
Energy can change from one state to another.
Energy can be neither created nor destroyed.
When energy changes from one form to another, some of it is lost.
The total amount of energy remains constant in an isolated system.
