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

Back

The unit of force is the Newton (N).

How do you determine if forces are balanced?

Back

Forces are balanced if the net force acting on an object is zero.

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, resulting in a net force greater than zero.

If an object has a mass of 10 kg and is accelerating at 3 m/s², what is the force acting on it?

Back

Force = mass × acceleration = 10 kg × 3 m/s² = 30 N.

In a tug of war, if one team pulls with a force of 60 N to the left and the other team pulls with a force of 50 N to the right, what is the net force?

Back

Net force = 60 N left - 50 N right = 10 N left.

What does it mean for an object to be at rest?

Back

An object is at rest when the net force acting on it is zero, resulting in no acceleration.

Front

How can you tell which direction an object will move when multiple forces are applied?

Back

The object will move in the direction of the net force, which is the vector sum of all applied forces.

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
