Question 1 of 10

### What is kinetic energy?

The energy of motion

Kinetic energy is energy of motion. Objects that are moving, such as a roller coaster, have kinetic energy (KE). How Force, Power, Torque and Energy Work

A measure of how much work an object can do

The amount of matter an object or body contains

None of the above

Question 2 of 10

### The standard unit for force is name after what person?

Albert Einstein

Isaac Newton

To honor Newton's achievement, the standard unit of force in the SI system was named the newton. How Force, Power, Torque and Energy Work

James Metric

None of the above

Question 3 of 10

### Weight is measured in what unit?

Grams

Pounds

All of the Above

A kilogram is the amount of weight at which 1 N of force will accelerate at a rate of 1 m/s2. In English units, a slug is the amount of mass that 1 pound of force will accelerate at 1 ft/s2, and a pound mass is the amount of mass that 1 lb of force will accelerate at 32 feet/s2. How Force, Power, Torque and Energy Work

Question 4 of 10

### The formula for calculating torque is:

Mass x acceleration

Force x distance

Torque equals force multiplied by distance. How Force, Power, Torque and Energy Work

Distance x acceleration

None of the above

Question 5 of 10

### The formula for calculating force is:

Mass x acceleration

That is, the more force you apply to an object, the greater the rate of acceleration; and the more mass the object has, the lower the rate of acceleration. Newton's Second Law is usually summarized in equation form: Force=Mass x Acceleration. How Force, Power, Torque and Energy Work

Energy x distance

Acceleration x distance

Question 6 of 10

### The International Systems of Units is also referred to as:

The metric system

Throughout this article, we will refer to different types of units. In most of the world, the International System of Units (SI - from the French Le Système International d'Unités), also referred to as the metric system, is accepted as the standard set of units. How Force, Power, Torque and Energy Work

The English Engineering Units

None of the above

Question 7 of 10

### What is energy?

A measure of how much work an object can do

Energy is a measure of how long we can sustain the output of power, or how much work we can do. How Force, Power, Torque and Energy Work

A force that tends to rotate or turn things

The amount of matter an object or body contains

Question 8 of 10

### What is torque?

The amount of matter an object or body contains

A force that tends to rotate or turn things

Torque is a force that tends to rotate or turn things. You generate a torque any time you apply a force using a wrench. How Force, Power, Torque and Energy Work

A measure of how much work an object can do

All of the above

Question 9 of 10

### Weight is a term used to describe:

Energy

Torque

Force

One type of force that everyone is familiar with is weight. This is the amount of force that the Earth exerts on you. How Force, Power, Torque and Energy Work

None of the above

Question 10 of 10

### What is mass?

The amount of matter an object or body contains

Generally, mass is defined as the measure of how much matter an object or body contains -- the total number of subatomic particles (electrons, protons and neutrons) in the object. How Force, Power, Torque and Energy Work

A force that tends to rotate or turn things

A measure of how much work an object can do

None of the above
