Physics 2

Question 1

Distance

Answer 1

The length of the space between one point and another.

Question 2

Speed

Answer 2

The distance travelled per unit of time.

Question 3

Time

Answer 3

A measurable period in which events or an event occurs.

Question 4

Scalar

Answer 4

A physical quantity that has magnitude only. For example, time.

Question 5

Vector

Answer 5

A physical quantity that has both magnitude and direction.

Question 6

Displacement

Answer 6

The Distance in a given direction. For example, 50 m north east. It is also the shortest distance between two points.

Question 7

Velocity

Answer 7

Speed in a given direction. For example, 100 km/h south. Velocity of an object can be calculated by dividing the displacement of an object by the time taken to undergo that displacement.

Question 8

Distance-time graph

Answer 8

Shows the distance something travels over the time taken to travel that distance. It is normally drawn by plotting the distance travelled on the y-axis and the time taken for the journey on the x-axis.
