SC.6.P.13.3 Unbalance Forces

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or change its motion because the forces acting on it are not equal in size and opposite in direction.

Front

What is a 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 acceleration.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

If a car is traveling at a constant speed, what can we say about the forces acting on it?

Back

The forces acting on the car are balanced, resulting in a net force of zero.

Front

Calculate the net force: 50 N to the right and 30 N to the left.

Back

Net Force = 50 N - 30 N = 20 N to the right.

Front

What is the net force if two equal forces of 20 N are acting in opposite directions?

Back

Net Force = 20 N - 20 N = 0 N, Balanced.

Front

If a person pushes a box with a force of 10 N to the right and another person pushes with 5 N to the left, what is the net force?

Back

Net Force = 10 N - 5 N = 5 N to the right.

Front

What is the effect of an unbalanced force on an object?

Back

An unbalanced force causes an object to accelerate, change direction, or change shape.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

If a net force of 0 N is acting on an object, what can we conclude?

Back

The object is either at rest or moving at a constant velocity.
