Forces And Motion

Front 1

Distance

Back 1

The length of the path of motion between two points.

Front 2

Displacement

Back 2

The length an object has moved in a specified direction; over the
shortest possible path of motion.

Front 3

Velocity

Back 3

The rate of displacement over time.
Measured in metres per second, m/s, or ms-1.

Front 4

Acceleration

Back 4

The rate at which velocity changes over time.
Measured in metres per second per second, m/s2, m/s/s, ms-2.

Front 5

Average Velocity

Back 5

The overall displacement divided by the total time elapsed.

Front 6

Constant velocity

Back 6

Velocity which remains the same; therefore acceleration is 0 ms-2.

Front 7

Constant Acceleration

Back 7

Acceleration where the velocity increases by the same amount
each time period, e.g. each second. Not to be confused with
constant velocity.

Front 8

Motion Path

Back 8

A set of points through which an object moves.

Front 9

Gravitational Acceleration

Back 9

9.81 m/s/s or
ms–2 or m/s2.

Front 10

Newton’s First Law of Motion

Back 10

States that an object will remain at rest or
in its current state of straight line motion at constant speed unless acted
on by an unbalanced force.

Front 11

Newton’s Third Law of Motion

Back 11

Indicates that in the motion of objects,
every action has an equal and opposite reaction.

Front 12

Newton's Second Law

Back 12

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
