Newton Laws

Front

What is a balanced force?

Back

A balanced force is a force pair that has a net force of zero, meaning the forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a net force greater than zero, causing an object to accelerate in the direction of the net force.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate force using mass and acceleration?

Back

Force can be calculated using Newton's second law: F = m × a, where F is force, m is mass, and a is acceleration.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = m × a).

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

If a 20 kg bike accelerates at 10 m/s², what is the force?

Back

200 N (calculated using F = m × a).

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.
