Newton's First Law

Question 1

What is Newton’s first law?

Answer 1

An object will stay at rest or continue to move at a constant velocity in a straight line unless acted upon by an external net (resultant) force.

Question 2

3 Important facts about Inertia

Answer 2

• Inertia is not a force, just a characteristic of matter
• If an object has mass, it has inertia
• The mass of an object is the measure of its inertia i.e the larger the object, the more difficult it is to move from rest or to stop if its in motion

Question 3

The formula for Newton’s First Law of Motion

OR

Law of Inertia

Answer 3

Question 4

Explain static and dynamic equilibrium.

Answer 4

Static: When an object is stationary and the sum of all forces exerted on it equals zero.

Dynamic: Object is moving at a constant velocity and the sum of all forces exerted on it equals zero.
