Net Forces

Front

What is the definition of net force?

Back

Net force is the vector sum of all the individual forces acting on an object, determining the object's acceleration.

Front

How do you calculate net force when multiple forces are acting in the same direction?

Back

To calculate net force when multiple forces are acting in the same direction, you add their magnitudes together.

Front

What is the net force if two forces of 10 N and 15 N are acting in the same direction?

Back

The net force is 25 N in the direction of the forces.

Front

What happens to an object when the net force acting on it is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

During which conditions are forces considered balanced?

Back

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

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

If a toy car is moving at a constant speed, what can be said about the forces acting on it?

Back

The forces acting on the toy car are balanced.

Front

What is the net force if a 5 N force to the right and a 3 N force to the left are acting on an object?

Back

The net force is 2 N to the right.

Front

How can you determine if forces are balanced or unbalanced from a speed-time graph?

Back

If the speed of the object remains constant, the forces are balanced; if the speed changes, the forces are unbalanced.
