Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What happens to your mass if Earth's mass is cut in half?

Back

Nothing, mass is not affected by gravitational force.

Front

What is the SI unit used to measure force?

Back

Newtons.

Front

What is the difference between mass and weight?

Back

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

Front

What does a scale measure?

Back

A scale measures weight, which is the force of gravity acting on an object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = m × g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

How does distance affect gravitational force?

Back

The farther apart two objects are, the weaker their gravitational attraction.

Front

What is the relationship between gravity and the distance between two objects?

Back

Gravity decreases as the distance between two objects increases.
