Newton's 2nd Law MCHS

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = ma.

Front

What does 'net force' mean?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is equilibrium in physics?

Back

Equilibrium is the state in which the net force acting on an object is zero, resulting in no acceleration.

Front

If an object is moving at a constant velocity, what can be said about the net force acting on it?

Back

The net force acting on it is zero.

Front

What happens to the acceleration of an object if the net force acting on it is increased?

Back

The acceleration of the object increases.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given net force.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a stationary car, causing it to move.

Front

What is the acceleration of an object in free fall (ignoring air resistance)?

Back

The acceleration of an object in free fall is approximately 9.81 m/s² downward.

Front

What is inertia?

Back

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