Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

How do you calculate net force when two forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the net force when 8 N to the left and 4 N to the right are acting on an object?

Back

4 N Left.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion.

Front

What is an action force?

Back

An action force is the initial force exerted by one object on another.

Front

What is a reaction force?

Back

A reaction force is the force exerted by the second object back on the first object, equal in strength and opposite in direction.

Front

In the example of a swimmer pushing off the wall, what is the action?

Back

The swimmer pushes off the wall of the pool.

Front

Which object has the strongest gravitational force with the Sun?

Back

The object with more mass has a stronger gravitational force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero, and the object remains at rest or continues moving at a constant speed.
