Newton's Laws

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is inertia in the context of Newton's 1st Law?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the greater its inertia.

Front

How does Newton's 2nd Law of Motion relate force, mass, and acceleration?

Back

Newton's 2nd Law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is the significance of the term 'unbalanced force' in Newton's Laws?

Back

An unbalanced force is a force that causes an object to change its state of motion. It is necessary for acceleration to occur.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Can you give an example of Newton's 3rd Law in action?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the relationship between mass and inertia?

Back

Mass is a measure of the amount of matter in an object, and it directly relates to inertia; more mass means more inertia.

Front

How does friction affect motion according to Newton's Laws?

Back

Friction is a force that opposes motion, and it can be considered an unbalanced force that affects the acceleration of an object.

Front

What happens to a moving object in space when no forces act on it?

Back

According to Newton's 1st Law, it will continue to move in a straight line at a constant speed.

Front

What is the formula for calculating force using Newton's 2nd Law?

Back

The formula is F = ma, where F is force, m is mass, and a is acceleration.
