Energy And Work

Question 1

A unit used to measure energy and work. One calorie is equal to 4.18; one joule of work is done when a force of one newton moves an object one meter.

Answer 1

Joule

Question 2

Stored energy; The energy an object has due to its position, molecular arrangement, or chemical composition

Answer 2

Potential energy

Question 3

The energy of motion. A moving object has the most kinetic energy at the point where it moves the fastest

Answer 3

Kinetic energy

Question 4

A combination of the kinetic energy and potential energy an object has

Answer 4

Mechanical energy

Question 5

No matter how energy is transferred or transformed, all of the energy is still present somewhere in one form or another

Answer 5

Conservation of energy

Question 6

The rate at which work is done

Answer 6

Power

Question 7

The unit of measurement for power, which is equal to one joule of work done or energy transferred in one second. For example, a 75 W light bulb concerts electrical energy into heat and light at a rate of 75 joules per second

Answer 7

Watt

Question 8

The unit of measurement of power for engines and motors. One horsepower equals 745 watts

Answer 8

Horsepower

Question 9
