2nd Law of Motion

Front

What happens when unbalanced forces act on an object at rest?

Back

The object begins moving in the direction of the net force.

Front

Newton's second law of motion states that __________.

Back

Acceleration is calculated by dividing the force exerted on an object by the mass of the object.

Front

The units of acceleration, m/s², are equivalent to which?

Back

N/kg

Front

This equation goes with which law?

Back

Newton's second law of motion.

Front

A ball held in a person’s hand does not move, even though gravity is acting on it because __________.

Back

The force of gravity is balanced by the force exerted by the hand.

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.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What does 'net force' mean?

Back

The overall force acting on an object after all the forces are combined.

Front

What is inertia?

Back

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

Front

How does mass affect acceleration?

Back

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