Simple Harmonic Motion And The Reference Circle

Question 0

Total distance in 1 cycle

Answer 0

4 amplitudes

Question 1

(No retarding forces) the amplitude the same to either side of the equilibrium point

Answer 1

Undamped SHM

Question 2

What is the period of the motion in relation to the amplitude

Answer 2

INDEPENDENT!

Question 3

What does the period of a simple pendulum depend on?

Answer 3

Length

Gravitational field strength

Question 4

What does the period of a mass on a spring depend on?

Answer 4

Mass

Stiffness of stirring

Question 5

What is hookes law

Answer 5

Any time. Spring is deformed from it’s ordinary size, it exerts a force to resist that deformation

Question 6

When the amplitude of oscillation decreases

Answer 6

Damped SHM

Question 7

For a pendulum when does the object come to rest

Answer 7

When changing direction

Question 8

Pendulum

When is the object moving at the greatest speed

Answer 8

When the object is at the equilibrium point

Question 9

At which point in the cycle is the acceleration of a pendulums the greatest

Answer 9

at the ends of the motion

Question 10

Which point is the acceleration of a pendulum zero

Answer 10

At the equilibrium point

Question 11

In which direction is a mass on the pendulum accelerating when moving toward an endpoint

Answer 11

Toward equilibrium point

Question 12

In which direction is a mass on the spring accelerating when moving toward the equilibrium point

Answer 12

Toward the equilibrium point

Question 13

Describe the speed of the pendulum changes as it moves from one endpoint going to the opposite end point

Answer 13

The speed starts zero, increases continuously until the object reaches equilibrium point. It then begins to decrease continuously, becoming zero at the opposite end point.

Question 14

What forces directly responsible for the acceleration of a pendulum

Answer 14

Parallel component of the force of gravity

Question 15

How can the force responsible for the acceleration of a pendulum cause different accelerations at different points if it is a constant-magnitude force

Answer 15

The angle increases as the object approaches the endpoint - the vertical increases

Question 16

Which force is directly responsible for the acceleration pattern of a mass oscillating at the end of a spring?

Answer 16

The restoring force of spring

Hookes law

Question 17

What characteristic of the spring force produces the acceleration pattern experienced by the mass

Answer 17

The distance the spring deforms

x

Question 18

How is the pendulum or springs velocity compared to the acceleration change as the object moves through a cycle of motion

Answer 18

Inversely related

Question 19

Starting at an endpoint what does the velocity of the object look like

Answer 19

Sine graph

Question 20

Starting at the equilibrium point what does the velocity look like

Answer 20

Cosine graph

Question 21

Starting at an end point what does the acceleration of an object look like

Answer 21

Cosine graph

Question 22

Starting at equilibrium point what does the acceleration look like

Answer 22

Sine graph

Question 23

Real springs have mass. How will the true frequency differ from those given by the equations from mass oscillating on the end of an idealized massless spring?

Answer 23

Since the mass of the real spring will add to the total mass of the system, the period Will increase and the frequency will decrease

Question 24

If a pendulum clock is accurate at sea level will it gain or lose time when taken to high-altitude

Answer 24

At higher altitude gravity decreases this will cause the period of the pendulum to increase since it will take longer to swing back-and-forth o’clock will run slow and will lose time

Question 25

Does mass have a effect on the frequency of the pendulum

Answer 25

No

Question 26

How do you increase the frequency of oscillation for a pendulum

Answer 26

Decreased the length of the pendulum or move it to a location with a greater gravitational value

Question 27

Which point in a swing are you accelerating linearly

Answer 27

At every point except the equilibrium point. Each of those positions, the motion is somewhat vertical. This causes the gravitational force on it to have a nonzero component along the line of motion (FG parallel)

Question 28

Would a swing working deep space

Answer 28

No because the gravitational force is what causes the acceleration. Without it, the object would either not move at all or travel at a constant speed in a circular path

Question 29

How do you decrease oscillation in a spring

Answer 29

Replace the spring with a more flexible one so the spring constant is smaller or add mass

Question 30

What is the direction of acceleration on a spring

Answer 30

Downward because the downward force of gravity is larger than the upward force exerted by the spring

Question 31

Would a spring work any differently on the moon

Answer 31

No because the gravitational field strength does not affect the period of oscillation
