Newton's Laws

Front

What is Newton's First 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 Newton's Second 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 (F = ma).

What is Newton's Third Law of Motion?

Back

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

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

Objects with greater mass have greater inertia, meaning they are harder to accelerate or decelerate.

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

How does friction affect speed?

Back

More friction decreases speed, while less friction increases speed.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

If a 12-N net force is applied to a 3-kg object, what is the acceleration?

Back

The acceleration is 4 m/s².

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

Back

The relationship is described by Newton's Second Law: F = ma.
