Front

A ruler is used to measure the length of an object between 1mm and 1m.

Back

It helps in finding the size of small objects.

Front

The volume of an irregular object can be measured by placing it in a measuring cylinder full of water.

Back

The rise in water level equals the volume of the object.

Front

Speed is defined as the distance traveled per unit time.

Back

If speed changes, the object is accelerating.

Front

Distance is measured in mm, cm, m, or km, and time is measured in ms, s, minutes, or hours.

Back

Always convert units to make them equivalent.

Front

Velocity is the speed in a given direction.

Back

It tells us not just how fast something is moving, but where it's going.

Front

Acceleration is the rate of change of velocity.

Back

It can be calculated using the formula: a = (v - u) / t.

Front

In a distance-time graph, the gradient represents velocity.

Back

A horizontal line means the object is stationary.

Front

Mass is a measure of how much matter is in an object.

Back

It does not change regardless of location.

Front

Weight is the gravitational force on an object, measured in Newtons.

Back

Weight can be calculated using the formula: weight = mass × gravitational field strength.

Front

Density is defined as mass per unit volume.

Back

It can be calculated using the formula: density = mass / volume.
