Question 1

for a simple harmonic motion, when is the speed at it’s maximum?

Answer 1

at equilibrium

Question 2

when is speed zero for simple harmonic motion

Answer 2

at the maximum displacemnet (amiplitude)

Question 3

what is the restoring force?

Answer 3

it is the force that tries to bring the object back to equilibrium

Question 4

when looking at a osclilating motion graph, what is the acceleration and velocity when the position is at its (+A max)

Answer 4

the velocity is zero and it is a turning point, the acceleration is also at its max but it is negative and direction it back towards equilibrium

Question 5

when looking at osclilating motion graph, what is the acceleration and velocity when the position is at its (-A Max)

Answer 5

the velocity is zero, the acceleration is at it’s max but it is positive and directs the motion back to equilibrium

Question 6

when looking at osclilating motion graph, what is the acceleration and velocity when the position is at equilibrium

Answer 6

the velocity is at it’s peak and the acceleration is zero

Question 7

what corresponds to a high frequency for a spring?

Answer 7

a large k and a lower masses

Question 8

what corresponds to a low frequency for a spring?

Answer 8

a small k and a higher mass

Question 9

when corresponds to a high frequency for a pendulum

Answer 9

a shorter length

Question 10

what corresponds to a low frequency for a pendulum

Answer 10

a longer length
