Kinetic energy
The energy of something that is moving.
What is kinetic energy?
Stored energy.
What is the sum of kinetic energy and potential energy of the particles in matter due to their random motion?
Example of kinetic to potential energy.
Varies-
Throwing a ball in the air.
Blowing up a balloon
Storing water in a tank.
Rolling up a yoyo.
Climbing a tree.
True or false. If you toss a baton straight up, the total energy decreases as the baton rises.
False. Total energy in a system cannot change.
The two things that kinetic energy of an object depend on.
What is the mass and speed of the object?
What can have the greatest affect on potential energy of an object?
Changing the object's position.
What is the energy that is stored in the nucleus of an atom?
Nuclear energy.
Example of electric to thermal energy.
Flat iron
Electric toaster
Stove top
What law states that energy can TRANFORMS from one form to another, but cannot be CREATED nor DESTROYED.
The law of conservation of energy.
What effect does mass have on kinetic energy?
Increasing the mass of an object will increase the kinetic energy.
You are riding a skateboard down a halfpipe at what point do you have the most potential energy?
The top of the halfpipe.
What is the total energy of an object due to large scale motions and interactions?
Mechanical energy.
What is an example of chemical to electrical energy?
Varies-

Which type of energy is constant in a system?
What two factors make up velocity and what is it measured in?
Speed and direction. Meters per second. M/s
At what point on a rollercoaster do you have the least potential energy?
At the bottom of the ramp.
What is the energy that is produced by objects that vibrate?
Sound energy.
What is an chemical to thermal energy?
Varies-
Burn wood in a fireplace
Burn gasoline in a car's engine
What is the force that resists the motion of two surfaces that are touching?
Friction.
How does velocity effects kinetic energy?
Increasing the velocity of an object will increase the kinetic energy
When you pull on a rubberband what kind of potential energy do you have?
