Physical Science - Force & Motions

Speed refers to .....

• how fast an object is moving in terms of distance moved and time taken to move in.

• measure of speed in a given direction

• change in velocity

• forces that are not opposite and equal

Velocity is ...

• how fast an object is moving in terms of distance moved in time taken to move in.

• a measure of speed in a given direction.

• a push or pull

• work against motion

Velocity =

• change in distance / change in time

• change in velocity X change in time

• change in velocity / change in time

• final velocity - initial velocity / time

Distance =

• velocity X time

• speed X distance

• distance/time

• length X width

distance versus time graphs show __________.

• changes in time over distance.

• changes in acceleration over time

• changes in velocity over time

• changes in acceleration over speed

velocity is measured in ________/

• meters per second

• meters per mile

• miles per hour

• velocity per minute

distance is measured in _________.

• centimeters or inches

• seconds, minutes or hours

• meters or kilometers

• liters or grams

distance versus time graphs show __________.

• changes in velocity over time.

• changes in acceleration over time

• changes in time over distance

• changes in time over speed

Acceleration =

• initial velocity - time / distance

• initial velocity - final velocity / time

• final velocity - initial velocity / time

• distance - speed / time

Force is ___________.

• how fast an object is moving in terms of distance moved and time taken to move

• force of gravity acting on an object

• how much matter is in an object

• a push or pull
