Question 1

The image shows one complete cycle of a mass on a spring in simple harmonic motion.

Revolt · Accepted Answer

The net force is zero, so the acceleration is zero.

Question 2

Julian tests four springs and records the results in the table.Which lists the springs in order of increasing spring constant?

Revolt · Accepted Answer

W, Y, X, Z

Question 3

Mateo adds two labels to the Venn diagram shown to explain how velocity and acceleration change during simple harmonic motion.Label 1: Zero at the equilibrium positionLabel 2: Increases with increasing net force

Revolt · Accepted Answer

Label 1: ZLabel 2: Z

Question 4

A spring that has a spring constant of 440 N/m exerts a force of 88 N on a box. What is the displacement of the spring?

Revolt · Accepted Answer

0.2 m

Question 5

The graph represents the simple harmonic motion of a pendulum.

Revolt · Accepted Answer

C

Question 6

Trevor places a mass on a spring. When he releases it, the mass and spring move in simple harmonic motion.

Revolt · Accepted Answer

He could pull the mass down farther.

Question 7

How much force is needed to stretch a spring 1.2 m if the spring constant is 8.5 N/m?

Revolt · Accepted Answer

10.2 N

Question 8

As a mass on a spring moves farther from the equilibrium position, how do the velocity, acceleration, and force change?

Revolt · Accepted Answer

The velocity decreases, the acceleration increases, and the net force increases.

Question 9

Revolt · Accepted Answer

velocity

Question 10

Rana writes a summary about a mass on a spring in simple harmonic motion as it moves upward from the equilibrium position toward the maximum positive displacement.As the mass moves upward, the velocity is positive and decreasing while the acceleration is negative and decreasing.

Revolt · Accepted Answer

The acceleration should be increasing, not decreasing.
