Physics

Question 1

SCALARS

Answer 1

Measurements that have quantity but no direction e.g. distance (describes how far an object has traveled along a path)

Question 2

VECTORS

Answer 2

Quantity & direction e.g. displacement (describes how far an object has traveled from its starting point)

Question 3

SPEED

Answer 3

Describes how quickly something is moving ; found by dividing distance by time (scalar value)

Question 4

VELOCITY

Answer 4

Rate at which an object changes position ; found by dividing displacement by time (vector value)

Question 5

ACCELERATION

Answer 5

How quickly an object changes velocity

Question 6

FORCE

Answer 6

A push or pull that causes an object to move or change direction

Question 7

GRAVITY

Answer 7

The attraction of one mass to another mass

Question 8

NORMAL FORCE

Answer 8

Occurs when an object is resting on another object

Question 9

BUOYANT FORCE

Answer 9

The upward force experienced by floating objects

Question 10

NEWTONS 1ST LAW

Answer 10

An object that is at rest stays at rest and at object that is in motion stays in motion, unless acted by a force

Question 11

NEWTONS 2ND LAW

Answer 11

Force = Mass • Acceleration

Question 12

NEWTONS 3RD LAW

Answer 12

For every action, there is an equal & opposite reaction

Question 13

ENERGY

Answer 13

The capacity of an object to do work

Question 14

KINETIC ENERGY

Answer 14

The energy possessed by objects in motion

Question 15

POTENTIAL ENERGY

Answer 15

Possessed by objects that have the potential to be in motion due to their position

Question 16

CONDUCTION

Answer 16

Occurs when 2 substances are in contact w each other

Question 17

CONVECTION

Answer 17

Transfers energy through circular movement of air or liquids
