Balanced/Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion of an object.

Front

What happens when forces are balanced?

Back

When forces are balanced, an object does not change its motion; it either remains at rest or continues to move at a constant speed in a straight line.

Front

Give an example of balanced forces.

Back

A car waiting at a red light is an example of balanced forces.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, causing a change in the motion of an object.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, an object will accelerate, decelerate, or change direction.

Front

Give an example of unbalanced forces.

Back

A car accelerating around a mountain curve is an example of unbalanced forces.

Front

What is the effect of unbalanced forces on an object's speed?

Back

Unbalanced forces can cause an object to speed up, slow down, or change direction.

Front

What must happen for an object to change its speed or direction?

Back

The forces acting on the object must be unbalanced.

Front

When an object continues to move in the same direction at the same speed, what type of forces are acting on it?

Back

Balanced forces are acting on the object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
