v² - u² = 2as

Question 8

Which equation links Acceleration, Initial Velocity, Final Velocity and Time?

Answer 8

a = v-u / t

Question 9

Answer 9

m (metres)

Question 10

What units is Velocity in?

Answer 10

m/s (Metres per second)

Question 11

What units is Acceleration in?

Answer 11

m/s² (metres per second squared)

Question 12

What units is Time in?

Answer 12

s (seconds)

Question 13

What does the gradient of a line on a distance time graph represent?

Answer 13

The speed

Question 14

What does it mean when the line is horizontal on a distance time graph?

Answer 14

the object is stationary

Question 15

What does it mean when the line is sloping upwards on a distance time graph?

Answer 15

the object is moving at a constant velocity

Question 16

What is displacement?

Answer 16

Displacement is distance in a given direction

Question 17

What is velocity?

Answer 17

Velocity is speed in a given direction

Question 18

What is acceleration?

Answer 18

The rate at which an object increases in velocity

Question 19

Describe the velocity of an object travelling around in a circle at a constant speed.

Answer 19

Although it may be travelling at a constant speed its velocity will not be constant as the direction in which it is moving is constantly changing.

Question 20

What is deceleration?

Answer 20

The rate at which an object decreases in velocity

Question 21

What is the equation that links Force, Mass and Acceleration?

Answer 21

F = M x A

Question 22

What is the equation to find weight?

Answer 22

W = M x G (Weight = Mass x gravitational Field Strength)

Question 23

What is Force Measured in?

Answer 23

Newtons (N)

Question 24

What is Mass measured in?

Answer 24

Kilograms (KG)

Question 25

What is Weight Measured in?

Answer 25

Newtons (N)

Question 26

What is weight?

Answer 26

Weight is the downward force exerted by an object due to its mass and the gravitational pull of a planet

Question 27

What is mass?

Answer 27

Mass is the amount of matter in a substance. It is measured in kilograms

Question 28

What does the gradient of a line on a velocity time graph represent?

Answer 28

Acceleration

Question 29

What does it mean when the line is horizontal on a velocity time graph?

Answer 29

It is travelling at a constant speed

Question 30

What does it mean when the gradient is negative on a velocity time graph?

Answer 30

The object is decelerating

Question 31

What does the area under the line on a velocity time graph represent?

Answer 31

The displacement of the object

Question 32

How do you find the speed of an object

travelling at increasing speed at a certain moment on a distance time graph?

Answer 32

You draw a tangent to the point at the moment you want to calculate the speed. You then calculate the gradient of the tangent.
