Resultant Forces & Vectors I

Front

What is the net force when two forces act in the same direction?

Back

The net force is the sum of the two forces.

Front

What is the net force when two forces act in opposite directions?

Back

The net force is the difference between the two forces, acting in the direction of the larger force.

Front

Define balanced forces.

Back

Balanced forces are forces of the same size acting in opposite directions, resulting in no change in motion.

Front

Define unbalanced forces.

Back

Unbalanced forces are forces that cause a change in motion, resulting in acceleration.

Front

What is a force?

Back

A force is a push or pull on an object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the resultant force in a tug of war where one team pulls with 200N to the left and the other with 150N to the right?

Back

The resultant force is 50N to the left.

Front

If a car is stationary, what can be said about the forces acting on it?

Back

The forces acting on the car are balanced.

Front

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

Back

The object remains at rest or continues to move at a constant speed.

Front

What is the effect of a net force acting on an object?

Back

A net force causes the object to accelerate in the direction of the net force.
