An object's change in position relative to a reference point.
What is motion?
100
The kinetic energy of a substance's atoms (heat).
What is thermal energy?
100
This type of energy occurs when a roller coaster is going down a hill.
What is kinetic energy?
100
This caused the marbles to slow down before the other bouncy ball and stress ball.
What is carpet and friction?
200
This occurs around the same time that thermal energy occurs. It is a force that opposes motion between two surfaces that are in contact.
What is friction?
200
The speed of an object in a particular direction.
What is velocity?
200
the energy of moving electrons.
What is electrical energy?
200
This type of energy is occurring when you freeze during a jumping jack.
What is potential energy?
200
In our ramp lab, this ball rolled the furthest and why.
What is the foam stress ball? Due to the carpet, size of the ball, and light weight of the ball?
300
A change from one form of energy to another.
What is energy conversion?
300
The difference between acceleration and speed.
What is the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change vs. the distance traveled divided by the time interval during which motion occurred?
300
The energy of a compound that changes as its atoms are rearranged.
What is chemical energy?
300
Name the types of energy that are occurring when you are ready to throw a ball, when the ball is in the air, and when the ball hits the ground.
What is potential, kinetic, kinetic (bounce)/potential?
300
Name the order that the objects would roll on carpet, from shortest distance to furthest distance: small marble, foam stress ball, large marble, bouncy ball.
What is small marble, large marble, bouncy ball, and foam stress ball?
400
Define nuclear energy.
What is energy that comes from changes in the nucleus of an atom?
400
The difference between mass and weight.
What is a measure of the amount of matter in an object vs. a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe? *Mass same everywhere, weight changes, for example, on the moon*
400
The amount of work an object can do because of the object's kinetic and potential energies.
What is mechanical energy?
400
The definition for potential energy.
What is the energy that an object has because of the position, shape, or condition of the object?
400
Name the order that the objects would roll on hardwood floor, from shortest distance to furthest distance: small marble, foam stress ball, large marble, bouncy ball.
What is foam stress ball, bouncy ball, large marble, small marble?
500
Define energy efficiency.
What is a comparison of the amount of energy before a conversion with the amount of useful energy after a conversion?
500
Name the law of conservation of energy.
What is the law that states that energy cannot be created or destroyed but can be changed from one form to another?
500
The difference between light and sound energy.
What is energy produced by the vibrations of electrically charged particles (light energy) vs. the energy caused by an object's vibrations (sound energy)?
500
The definition for kinetic energy.
What is the energy of an object that is due to the object's motion?
500
Name five factors that may affect how far an object would roll.
What is surface, texture, size, mass, height of ramp?
