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 a net external force.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) is calculated using the formula a = F/m, where F is the net force applied and m is the mass of the object.

Front

What does Newton's Second Law of Motion 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 the significance of balanced forces?

Back

Balanced forces result in no change in motion; the object remains at rest or continues to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force causes a change in the motion of an object, resulting in acceleration.

Front

How does Newton's Third Law of Motion apply to action-reaction pairs?

Back

For every action, there is an equal and opposite reaction; forces always occur in pairs.

Front

What is the role of friction in motion?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by vectorially adding all the individual forces acting on an object.

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 acceleration?

Back

A larger mass results in a smaller acceleration for the same amount of force applied, according to Newton's Second Law.
