Flashcards in Science 10 - Motion Deck (14):
1

What is distance?

The amount of space between two objects or points.

2

What is speed?

The distance travelled per unit of time. 10m/s 110km/h

3

What is displacement?

The change in position. 250km[N]

4

What is position?

The separation and direction from the reference point. 152m[W]

5

What is velocity?

A speed along with a direction. 60km/h[E]

6

What is air resistance?

Friction of air/force of air on moving object, alters speed.

7

What is g-force (acceleration)?

The acceleration of falling objects due to the force of gravity.

8

What is terminal velocity?

When a falling object is no longer accelerating because the upward and downward force are balanced.

9

What is vector quantity?

A quantity that has both size and direction

10

What is scalar quantity?

A quantity that involves only size.

11

What is constant velocity?

Speed and direction stays the same.

12

What is constant speed?

Speed stays the same, but direction may change.

13

Average velocity?

v(arrow)=deltaDr(arrow) divided by time

14

Average speed?

v=d/t
