Force and Acceleration

Question 1

Newton’s First Law

Answer 1

An object at rest will remain at rest and a moving object will continue moving at constant velocity as long as no resultant force acts on the object.

Question 2

What is needed for velocity of an object to change?

Answer 2

An unbalanced/resultant force.

Question 3

What is inertia?

Answer 3

The tendency of objects to continue in their state of rest or of uniform motion is called inertia.

Question 4

State Newton’s Second Law

Answer 4

The acceleration of an object is proportional to the resultant force acting on the object, and inversely proportional to the mass of the object.

Question 5

What is the word equation for Newton’s Second Law?

Answer 5

Resultant force = mass x acceleration

Question 6

What is inertial mass?

Answer 6

A measure of how difficult it is to change the velocity of an object. It is defined as the ratio of force over acceleration.

Question 7

State Newton’s Third Law

Answer 7

Whenever 2 objects interact, the forces they exert on each other are equal and opposite.
