Q

Work

A

What is done when a force moves an object over a distance

17
Q

Balanced Forces

A

When 2 opposing forces are equal; net force = on

18
Q

Calibrations

A

The marks or spaces that create an even scale for measurement

19
Q

Distance

A

How far apart 2 points are; length, width, height, breadth

20
Q

Extrapolate

A

To look beyond the end of a line graph to predict data

21
Q

Force

A

Something which makes an object speed up, slow down, stop, change direction or change its shape

22
Q

Force Meter

A

Also called a Newton meter, measures force

23
Q

Friction

A

The force created when surfaces or molecules rub together

24
Q

Inertia

A

The resistance of an object to be moved once at rest

25
Q

Interpolate

A

To look between the data points in a line graph to figure out data points

26
Q

Joules

A

The unit of energy

27
Q

Kinetic Energy

A

The energy found in all moving objects

28
Q

Line Graph

A

Most common graph used in physics, data is to be plotted using small crosses, then either joined or a line of best fit is drawn

29
Q

Line of best fit (LOBF)

A

A line which is drawn to show the trend of data, it does not go through each data point

30
Q

Mass

A

The amount of matter in an object, measured in kgs

31
Q

Momentum

A

The measure of the mass in an object times (x) its velocity, objects in motion tend to stay in motion

32
Q

Motion

A

The act of moving
