Motion and Forces- Work and Energy

Question 1

The unit to measures energy and work. One calorie is equal to 4.18 joules of energy; one joule of work is done when a force of one Newton moves an object on meter.

Answer 1

Joule

Question 2

Stored energy; the energy an object has to 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 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 which work is done

Answer 6

Power

Question 7

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

Answer 7

Watt

Question 8

The use of force to move an object over a distance

Answer 8

Work
