6th Science Topic 3 Review

What is energy?

• Energy is the force on an object that causes it to change its motion in the same direction in which you exert the force.
• Energy is a push or pull.
• Energy is the ability to do work or cause change.
• Energy is the amount of work done on an object.

What are some examples of forms of energy?

• Work, force, and motion are all forms of energy.
• Light, sound, and electricity are all forms of energy.
• Newtons, meters, and joules are all forms of energy.
• Units, watts, and power are all forms of energy.

What is force?

• A force is the energy of an object that causes it to change its motion in the same direction in which you exert the force.
• A force is a push or a pull.
• A force is the ability to do work or cause change.
• A force is the amount of work done on an object.

What is work?

• Work is a push or pull.
• Work is the amount of energy being transferred to an object.
• Work is the force exerted on an object that causes it to move.
• Work is the ability to cause a temperature change in an object.

What is kinetic energy?

• Kinetic energy is stored energy.
• Kinetic energy is mechanical energy being transformed.
• Kinetic energy is the energy that an object possesses by virtue of being in motion.
• Kinetic energy is virtue energy.

What determines an object’s kinetic energy?

• The kinetic energy of an object depends on its weight and volume.
• The kinetic energy of an object depends on its temperature and state of matter.
• The kinetic energy of an object only depends on how fast it is moving.
• The kinetic energy of an object depends on both its speed and mass.

What is potential energy?

• Energy where motion is involved.
• Energy that results from the position or shape of an object is potential energy.
• Energy that an object possesses by virtue of being in motion.
• Energy that depends on an object's speed and mass.

What does potential energy have the potential to do?

• To destroy the total energy in a system.
• To transfer energy into waves.
• To transform into kinetic energy or to do work.
• To transform into gravitational potential energy.

What are the 3 factors that determine an object’s mechanical energy?

• Mass, speed, velocity, or a combination of these factors
• Weight, gravity, distance, or a combination of these factors
• Motion, shape, position, or a combination of these factors
• Temperature, state of matter, speed, or a combination of these factors

What is nuclear energy?

• Nuclear energy s the energy an object has due to its motion, shape, position, or a combination of these factors.
• Nuclear energy is a type of potential energy stored in the nucleus of an atom.
• Nuclear energy is the total potential and kinetic energy of particles in an object.
• Nuclear energy is the energy of electric charges.
