Who discovered Gravity?

Back

Sir Isaac Newton is credited with the discovery of the law of universal gravitation.

What is the difference between Mass and Weight?

Back

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

Front

What is the 1st Law of Motion?

Back

The 1st Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a force.

Front

What is the 2nd Law of Motion?

Back

The 2nd Law of Motion states that force equals mass times acceleration (F=ma).

Front

What is the 3rd Law of Motion?

Back

The 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What is an example of Gravity in action?

Back

An example of gravity in action is when an apple falls from a tree to the ground.

Front

How does Gravity affect planets?

Back

Gravity keeps planets in orbit around the sun and moons in orbit around planets.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = Mass x Gravity.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².
