10 Terms

1

What is Newton's First Law of Motion?

An object will remain at rest or in uniform motion unless acted upon by an external force.

New cards
2

What is the formula for Newton's Second Law of Motion?

F = ma (Force equals mass times acceleration).

New cards
3

How does Newton's Third Law of Motion state forces interact?

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

New cards
4

What does inertia refer to in Newton's First Law?

Inertia is the tendency of an object to resist changes in its state of motion.

New cards
5

What is the significance of mass in Newton's Second Law?

Mass is a measure of the amount of matter in an object, affecting its acceleration when a force is applied.

New cards
6

Give an example of Newton's Third Law in everyday life.

When you push against a wall, your hand exerts a force on the wall, and the wall exerts an equal and opposite force back on your hand.

New cards
7

What real-life scenario illustrates Newton's First Law?

A stationary book on a table remains still until someone pushes it.

New cards
8

How can you increase acceleration according to Newton's Second Law?

You can increase acceleration by either increasing the force applied or decreasing the mass.

New cards
9

What happens to a projectile during its flight in relation to Newton's laws?

It experiences force of gravity acting downward and air resistance acting in the opposite direction.

New cards
10

Explain the relationship between force and motion in Newton's laws.

Forces cause changes in motion, with their effects quantified by Newton's laws, defining how objects behave under different force conditions.
