What is inertia, and why is it important in the laws of motion?

Determine the moments of inertia and the product of inertia of the beam's cross-sectional area with respect to the $u$ and $v$ axes.

Describe what the moment of inertia measures. Explain how it is used to find the polar moment of inertia.

Which causes an object in motion to remain in motion?

A. friction

c. inertia

B. gravity

D. velocity

Summarize Newton's three laws of motion.

Was it Galileo or Newton who first proposed the concept of inertia?

explain how newton's law of inertia describes the motion of objects.

Apply Concepts: What is inertia? Use an example in your description.

Solve the linear system using elimination.

$$\begin{array} { l } { - x + \frac { 1 } { 2 } y = - 19 } \\ { x - y = 12 } \end{array}$$

Inertia depends on mass; rotational inertia depends on mass and something else. What?

What is the unit of measure of force, and how is it related to other measurement units?

Newton's first law of motion states any of the following except a. an object at rest remains at rest unless it experiences an unbalanced force. b. an object in motion maintains its velocity unless it experiences an unbalanced force. c. an object will tend to maintain its motion unless it experiences an unbalanced force. d. an object will tend to maintain its motion unless it experiences a balanced force.

Which of the following changes when an unbalanced force acts on an object?

A) mass

C) inertia

B) motion

D) weight

What is the difference between free fall and weightlessness?
