Question 11

Determine how many significant figures to answer to

Answer 11

Answers are rounded to the least precise unit of the numbers provided

Question 12

True or False: Negative acceleration is the same as deceleration

Answer 12

False. Negative acceleration is acceleration in the negative direction of the chosen coordinate system while deceleration is acceleration in the opposite direction of motion

Question 13

(SUVAT) v =…

Answer 13

v = u+at

Question 14

(SUVAT) v^2 =…

Answer 14

v^2 = u^2+2as

Question 15

(SUVAT) s =…

Answer 15

s = t/2(u+v)
= ut+1/2at^2
= vt-1/2at^2

Question 16

Explain how to find the distance/displacement from the speed/velocity-time graph

Answer 16

The area formed by the shape of the journey is the distance/displacement

Question 17

Explain how to find the acceleration from the speed/velocity-time graph

Answer 17

The gradient is the acceleration

Question 18

Recall the equation for change in direction

Answer 18

Vector b - Vector a

Question 19

Identify the trig function for the horizontal component

Answer 19

The trig function for the horizontal component is cosine

Question 20

Identify the trig function for the vertical component

Answer 20

The trug function for the vertical component is sine

Question 21

W =…

Answer 21

W=mg

Question 22

F =…

Answer 22

F=ma

Question 23

On a slant, recall whether mg*sin(theta) is perpendicular or parallel to the object

Answer 23

mg*sin(theta) is parallel

Question 24

On a slant, recall whether mg*cos(theta) is perpendicular or parallel to the object

Answer 24

mg*cos(theta) is perpendicular

Question 25

Recall what type of wave does not require a medium

Answer 25

Electromagnetic waves do not require a medium

Question 26

(Waves) v =...

Answer 26

v=fλ

Question 27

Recall what type of wave had compressions and rarefactions

Answer 27

Longitudinal waves have compressions and rarefactions

Question 28

Recall the shape of the wave created by simple harmonic motion

Answer 28

Simple harmonic motion forms a sinusoidal wave

Question 29

For a displacement-distance graph, express the motion of the wave as an equation

Answer 29

y=Asin(kx) where k is 2π/λ

Question 30

For a displacement-time graph, express the motion of the wave as an equation

Answer 30

y=Asin(wt) where w is 2π/T

Question 31

Contrast the reflected waves from a rigid and flexible boundary

Answer 31

The waves reflected are opposite in polarity and free to move vertically respectively

Question 32

Recall what impacts the velocity of a wave?

Answer 32

The velocity of a wave is impacted by the density of the medium it is traveling through

Question 33

Contrast a ray and a wavefront

Question 34

Recall what impacts the frequency of a wave?

Answer 34

No factors impact the frequency
