Practice: Newton's Laws & Gravity 2024

Front

What is mass?

Back

The amount of matter in an object.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/sec².

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is air resistance?

Back

A type of friction that acts against the motion of an object moving through air.

Front

How does air resistance affect falling objects?

Back

It slows down lighter objects more than heavier ones, causing them to fall at different rates.

Front

What happens to an object's weight on different planets?

Back

Weight changes based on the planet's gravity, but mass remains constant.
