Question 1

What is the formula for calculating force?

Accepted Answer

Force = mass × acceleration

Answer

Force = mass ÷ acceleration

Answer

Force = mass - acceleration

Answer

Force = mass + acceleration

Question 2

What is inertia?

Accepted Answer

The tendency of an object to resist changes in its motion.

Answer

The rate at which an object's velocity changes over time.

Answer

The force exerted on an object due to gravity.

Answer

The resistance of an object to being moved.

Question 3

What is the law of conservation of momentum?

Accepted Answer

The total momentum of a closed system remains constant if no external forces act on it.

Answer

The speed of any object in motion remains constant unless acted upon by an external force.

Answer

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Answer

The acceleration of an object is directly proportional to the net force applied to it.

Question 4

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

Accepted Answer

Force = mass × acceleration

Answer

Force = mass + acceleration

Answer

Force = mass - acceleration

Answer

Force = mass ÷ acceleration
