Question 0

Define speed

Answer 0

The measurement of the rate of change in distance. Speed is a scalar quantity and can be expressed in a number of units.

Question 1

Define Velocity

Answer 1

The measurement of the rate of change in displacement. It is a vector quantity and should only be expressed in the S.I units of displacement and time

Question 2

All components needed for acceleration questions

Answer 2

Final velocity (v)
Initial velocity (u)
Time (t)
Acceleration (a)

Question 3

What does a constant acceleration produce

Answer 3

A straight line or linear slope (rise/run)

Question 4

Who invented acceleration?

Answer 4

Galileo during the 1600’s

Question 5

What is a vector quantity

Answer 5

Require a direction to be meaningful

Also a magnitude and a unit

Question 6

What is a scaler quantity

Answer 6

Scaler quantities require only a magnitude and a unit for it to be meaningful

Question 7

What is distance?

Answer 7

Distance is a scalar quantity. It is the total amount traveled by an object from start to finish.

Question 8

What is displacement?

Answer 8

Displacement is a vector quantity. It is the measurement of how far an object is from where it started

Question 9

Convert km/h to m/s

Answer 9

x 1000 then divide 3600

Question 10

What are S.I. Units

Answer 10

It stands for Scientific international

Standard units of measurement of physical properties

Question 11

Convert m/s to km/h

Answer 11

Divide 1000 then x 3600

Question 12

The rate of which velocity changes occur is called what?

Answer 12

Acceleration

Question 13

Define Newtons 1st Law

Answer 13

An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force

Question 13

Define Balance Force

Answer 13

Equal forces in opposite directions that produce no motion

Question 13

Define Unbalanced force

Answer 13

Unequal opposing forces produce an unbalanced force causing motion

Question 13

Define motion

Answer 13

The action or process of being moved

Question 14

Define Mass

Answer 14

The amount of matter in an object

Question 15

4 types of friction

Answer 15

Sliding
Fluid
Rolling
Static

Question 16

Define Friction

Answer 16

the unbalanced force that acts on an object in motion

Question 17

Define Newton’s second law

Answer 17

Net force

Question 18

What’s happens when a balanced force acts on an object

Answer 18

1. Remain stationary

2. Continue with a constant velocity

Question 19

Define Energy

Answer 19

The ability to do work on an object

Question 20

Define momentum

Answer 20

When any object has a mass and velocity it is said to have momentum

Question 25

Define Newton’s third law

Answer 25

For every action there is an equal and opposite reaction
