Exam 10: Force and Force-Related Variables in Engineering

What does $\mu$ stand for in the following equation? $F _ { \max } = \mu N$

A force tends to cause an object to accelerate. The force and the resulting acceleration have

What does W stand for in the following equation? $W = m g$

In general, the viscosity of gases increases with increasing temperature.

All forces result from direct contact.

A force that will accelerate 1 kilogram of mass at a rate of $1 \mathrm {~m} / \mathrm { s } ^ { \mathrm { 2 } }$ is known as a

What does G stand for in the following equation? $F = \frac { G m _ { 1 } m _ { 2 } } { r ^ { 2 } }$

Weight and mass are essentially the same thing.

If an object is moving and there are no unbalanced forces acting on it, the object will

What does F stand for in the following equation? $F = \frac { G m _ { 1 } m _ { 2 } } { r ^ { 2 } }$

What does g stand for in the following equation? $W = m g$

Objects at rest tend to remain at rest and objects in motion tend to remain in motion, unless acted upon by an unbalanced external force. This is a basic description of a. Newton's $1 ^ { \text {st } }$ Law. b. Newton's $2 ^ { \text {nd } }$ Law. c. Newton's $3 ^ { \text {rd } }$ Law. d. Newton's $4 ^ { \text {th } }$ Law.

The quantity that represents a measure of how easily a given fluid can flow is known as

If you push on the wall with a force of 10 pounds, the wall pushes back on you with a force of 10 pounds. This is a basic description of a. Newton's $1 ^ { \text {st } }$ Law. b. Newton's $2 ^ { \text {nd } }$ Law. c. Newton's $3 ^ { \text {rd } }$ Law. d. Newton's $4 ^ { \text {th } }$ Law.

A tow truck exerts a force of 2000 N on a car, causing it to accelerate at $3 \mathrm {~m} / \mathrm { s }$ . What is the mass of the car?

A force of 10N causes a spring to stretch 50cm. What is the spring constant? a. $500 \mathrm {~N} \cdot \mathrm { cm }$ b. $0.2 \mathrm {~N} / \mathrm { m }$ c. $5 \mathrm {~cm} / \mathrm { N }$ d. $20 ^ { \mathrm { N } } / \mathrm { m }$

A single force can exist all by itself.

Which of the following is the SI unit for force?

A tow truck exerts a force of 2000N on a car, causing it to accelerate at $4 \mathrm {~m} / \mathrm { s } ^ { 2 }$ . What is the mass of the car?

Force is a fundamental dimension.
