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 unless acted upon by a net external force.

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 Newton's Third Law of Motion?

Back

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

Front

Define inertia in the context of Newton's First Law.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the relationship between unbalanced forces and motion?

Back

An object will accelerate in the direction of the net unbalanced force acting on it.

Front

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

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

Explain the concept of action-reaction pairs in Newton's Third Law.

Back

Action-reaction pairs are forces that two objects exert on each other, equal in magnitude and opposite in direction.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces result in no change in the object's motion; it remains at rest or continues moving at a constant velocity.
