Energy, Motion Force & Work/ PE and KE Review

What is energy?

• The ability to do work or cause change

• The ability to see and observe

• The ability to create light and sound

• The ability to transfer from place to place

What are some forms of energy?

• Light, sound, and electricity

• Heat, water, and air

• Food, water, and air

• Motion, force, and work

What is work in science?

• When a force is exerted on an object that causes it to change its motion

• When an object is not moving

• When energy is transferred from one place to another

• When an object is in motion

What is kinetic energy?

• The energy of an object that is in motion

• The energy of an object at rest

• The energy of an object due to its position or shape

• The energy of an object that is changing

What factors affect kinetic energy?

• Speed and mass

• Force and work

• Potential energy and motion

• Light and sound

What is the law of conservation of energy?

• Energy cannot be created or destroyed, only transformed or transferred

• Energy can be created or destroyed, depending on the situation

• Energy is always conserved in a closed system

• Energy is only conserved in certain situations

What is potential energy?

• The energy of an object due to its position or shape

• The energy of an object that is in motion

• The energy of an object at rest

• The energy of an object that is changing

What is the relationship between work and energy?

• Work is the transfer of energy from one object to another

• Work and energy are unrelated concepts

• Work is a form of energy

• Energy is a form of work
