Practice: Newton's Laws & Gravity 2024

Front

What does Newton's Third Law state?

Back

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

Front

Which Law of Motion states that an object at rest stays at rest unless acted upon by a force?

Back

Newton's First Law of Motion.

Front

What is the acceleration due to gravity on Earth?

Back

9.8 m/sec².

Front

What is the formula to calculate weight?

Back

Weight = mass × acceleration due to gravity.

Front

If an object has a mass of 50 kg, what is its weight on Earth?

Back

490 N (Weight = 50 kg × 9.8 m/sec²).

Front

What is gravitational attraction?

Back

The force that pulls two objects toward each other, proportional to their masses.

Front

What is the acceleration due to gravity on Mars?

Back

3.7 m/sec².

Front

How does mass affect gravitational attraction?

Back

Greater mass results in greater gravitational attraction.

Front

What is the relationship between force, mass, and acceleration?

Back

F = m × a (Newton's Second Law of Motion).

Front

What happens to an object's motion if no net force acts on it?

Back

It will maintain its current state of motion (either at rest or moving at constant velocity).
