Forms of Energy
A stored form of energy
What is potential energy?
The process that occurs when the same form of energy changes places.
What is an energy transfer?
The total force acting on an object.
What is net force?
The time it takes for an object to move a certain distance.
What is speed?
The variable that is changed on purpose by the scientist.
What is the independent variable?
The form of energy that results from motion
What is kinetic energy?
The process that occurs when one form of energy changes into another form of energy.
What is an energy transformation?
The type of force that results in the rocket launching off the launch pad.
What is an unbalanced force?
The speed and direction an object travels.
What is velocity?
The variable that is measured based on manipulating something in an experiment.
What is the dependent variable?
The unusable energy that escapes many systems as an object moves
What is thermal energy?
The form of energy that is typically lost to the surroundings when energy transforms.
What is thermal energy?
The type of force that allows a satellite to travel through space at a constant velocity.
What is a balanced force?
The change in velocity in a given amount of time.
What is acceleration?
These ensure that the dependent variable is measured accurately, and the results of an experiment are precise.
What are constant variables?
This is one way that students could increase the amonut of potential energy in the rocket system
What is stomping on the launch pad harder? (Other answers are possible)
When the rocket is flying through the air, this is the force that makes PE --> KE less efficient.
What is air resistance?
This is an unbalanced force that causes an object to decrease in speed.
What is friction?
The force of air resistance acting on the stomp rocket causes this to happen.
What is deceleration?
distance / time
What is the formula for speed?
The force that transforms kinetic energy into thermal energy
What is friction?
The concepts that proves that the energy in the universe is constant.
What is the Law of Conservation of Energy?
The inertia of the stomp rocket will not change when this type of force is applied.
What is a balanced force?
Changing these two variables would change the velocity of the rocket according to the 2nd Law of Motion.
What is force and mass?
Force = mass x acceleration
What is the 2nd Law of Motion?
