Weight - Week 5

Front

What is weight?

Back

Weight is the force exerted by gravity on an object. It is measured in units like pounds (lbs) or kilograms (kg).

Front

How do we measure weight?

Back

Weight is measured using a scale, which can be digital or mechanical.

Front

What is the difference between weight and mass?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What unit is commonly used to measure weight in the metric system?

Back

The kilogram (kg) is the standard unit of weight in the metric system.

Front

What happens to weight on the Moon compared to Earth?

Back

Weight is less on the Moon because the Moon has weaker gravity than Earth.

Front

If an object weighs 10 kg on Earth, how much would it weigh on the Moon?

Back

It would weigh about 1.6 kg on the Moon.

Front

What is a scale?

Back

A scale is a device used to measure the weight of an object.

Front

What is the formula to calculate weight?

Back

Weight (W) = mass (m) × gravity (g). On Earth, g is approximately 9.8 m/s².

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

Can weight change?

Back

Yes, weight can change depending on the gravitational force acting on the object.
