Lesson 3-1 Energy, Motion, Work, and Force 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.

How do you know energy is being transferred?

• Energy is being transferred when the particles separate through distillation.
• Energy is being transferred when the temperature reaches 100 degrees Celsius.
• Energy is being transferred when ice forms into crystals.
• Energy is not something you can see directly, but you can observe its effects.

What does an object need for motion to occur?

• It takes energy for motion to occur.
• It takes work for motion to occur.
• It takes force for motion to ocur.
• It takes power for motion to occur.

How do you know when an object is in motion?

• An object is in motion if it is in a solid state.
• An object is in motion if its position changes relative to another object.
• An object is in motion if it changes temperature.
• An object is in motion if its particles are negatively charged.

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 beign 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.

When is the maximum amount of work done?

• The maximum amount of work is done when both the movement and the force are in the same direction.
• The maximum amount of work is done when the distance is the shortest amount.
• The maximum amount of work is done when the temperature is at its lowest.
• The maximum amount of work is done when heat is transferred to an object at rest.

How can you calculate power?

• Power is calculated by dividing the amount of work being done by the amount of time it takes to do the work
• Power is calculated by multiplying force and distance.
• Power is calculated by dividing the energy in joules by the temperature in Celsius.
• Power is calculated by multiplying the work by the loss of electrons.

How are power and energy related?

• Power is the state of matter that an object changes into.
• Power is the work being transferred to an object.
• Power is also the rate at which energy is transferred, or the amount of energy transferred in a unit of time.
• Power is the force being applied to an object.
