Physics Energy Part 1

What is the standard unit of energy?

• Newton (N)

• Joule (J)

• Watt (W)

• Pascal (Pa)

Which of the following best describes kinetic energy at the macroscopic level?

• Energy stored in chemical bonds

• Energy associated with the motion of an object's particles

• Energy stored in gravitational fields

• Energy associated with the position of an object's particles

What is the Greek origin of the word "energy"?

• Energeia

• Dynamis

• Kinesis

• Physis

Which of the following is an example of potential energy at the microscopic level?

• The motion of a car

• The heat from a stove

• The energy stored in the bonds between atoms

• The light from a bulb

What does the conservation of energy principle state?

• Energy can be created and destroyed

• Energy can change forms but cannot appear from nothing or disappear without a trace

• Energy is always increasing in the universe

• Energy is only present in living organisms

Which of the following is an example of energy transfer by a macroscopic mechanism?

• Heat transfer between two objects

• Chemical reaction in a battery

• Work done by lifting a box

• Light emission from a lamp

What is the relationship between energy and work in physical science?

• Energy is the ability to do work

• Work is the ability to create energy

• Energy and work are unrelated

• Work is the storage of energy

Which of the following describes the energy of particles at the microscopic level?

• Energy is only kinetic

• Energy is only potential

• Energy is both kinetic and potential

• Energy is neither kinetic nor potential
