Newtons 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 at a constant velocity unless acted upon by a net external force.

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

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 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, expressed as F = ma.

Front

What does the equation F = ma represent?

Back

It represents Newton's Second Law of Motion, where F is the net force, m is the mass, and a is the acceleration.

Front

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

Back

Force is the product of mass and acceleration; more force is needed to accelerate a heavier object.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Can you give an example of Newton's Third Law?

Back

When a swimmer pushes backward against the water, the water pushes the swimmer forward.

Front

What is the significance of the term 'net force'?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

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

Back

Friction is a force that opposes motion, affecting the net force and thus the acceleration of an object.
