Front

What is the net force acting on an object?

Back

The vector sum of all forces acting on the object.

Front

According to Newton's third law, for every action, there is an __________ reaction.

Back

equal and opposite

Front

How do you determine the net force acting on an object?

Back

By adding all the forces acting on the object, taking into account their directions.

Front

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

Back

Newton (N)

Front

If a net force of 3 N is acting to the right, what does this indicate?

Back

The object will accelerate to the right.

Front

What does it mean if the net force on an object is zero?

Back

The object is in equilibrium and will not accelerate.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

If an object has a net force of 1 N to the left, what can we infer about its motion?

Back

The object will accelerate to the left.

Front

What is the significance of the direction of the net force?

Back

It determines the direction of the object's acceleration.
