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 a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often summarized by the formula F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does inertia refer to in physics?

Back

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

Front

What is the formula for calculating force?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

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

Back

According to Newton's 2nd Law, force is the product of mass and acceleration (F=ma).

Front

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone applies a force to move it.

Front

How does Newton's 3rd Law apply to walking?

Back

When you walk, your foot pushes backward against the ground, and the ground pushes you forward with an equal and opposite force.
