Newton's laws of motion

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 a net external 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).

Front

What is Newton's Third Law of Motion?

Back

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

Front

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

As mass increases, inertia increases, meaning it becomes harder to change the object's state of motion.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

Force is the product of mass and acceleration; increasing mass while keeping force constant results in decreased acceleration.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction depends on the nature of the surfaces in contact and the normal force pressing them together.

Front

What is the direction of the friction force?

Back

The friction force acts in the opposite direction to the motion or attempted motion of an object.
