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 motion.

Front

What does it mean if the net force is 0 N?

Back

If the net force is 0 N, it means that all the forces acting on an object are balanced, and the object will not accelerate.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, causing an object to accelerate in the direction of the greater force.

Front

In a tug of war, if one team pulls with 100 N and the other with 80 N, what is the net force?

Back

The net force is 20 N in the direction of the team pulling with 100 N.

Front

What happens to an object when a net force acts on it?

Back

When a net force acts on an object, it causes the object to accelerate in the direction of the net force.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Force applied (F1) - Force opposing (F2) if they are in opposite directions.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

How does mass affect the net force?

Back

The greater the mass of an object, the greater the net force needed to accelerate it.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = m * a, where F is force, m is mass, and a is acceleration.
