Newtons 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 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. This is expressed as A = f/m.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the standard unit of force?

Back

Newtons (N).

Front

What is net force?

Back

The vector sum of all the forces acting on an object.

Front

How do you calculate acceleration?

Back

A = f/m, where A is acceleration, f is net force, and m is mass.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as W = mg, where m is mass and g is the acceleration due to gravity.

Front

What is an example of Newton's First Law?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

What is an example of Newton's Second Law?

Back

If you push a shopping cart, it accelerates in the direction of the push, and the acceleration depends on how hard you push and the mass of the cart.
