Newton's Laws & Forces

Front

What is Newton's First Law known as?

Back

The Law of Inertia

Front

What is the correct unit for weight?

Back

Newtons

Front

What does Newton's Second Law state?

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?

Back

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

Front

Define net force.

Back

Net force is the vector sum of all forces acting on an object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in the object.

Front

What happens to an object at rest according to Newton's First Law?

Back

An object at rest will remain at rest unless acted upon by a net external force.

Front

What happens to an object in motion according to Newton's First Law?

Back

An object in motion will continue in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the effect of increasing mass on acceleration when the same force is applied?

Back

Increasing mass will decrease acceleration (a = F/m).
