Net Forces

A toy car was used in an investigation about forces. During which of the following scenarios was the car experiencing balanced forces?

• The toy car speeds up as it rolls down a ramp.
• The toy car travels forward at a constant speed.
• The toy car slows down as it rolls up a hill.
• The toy car changes direction at a constant speed.

If there are two forces going in the same direction how would you find the net force?

• Subtract
• Add
• Neither
• Multiply

A cyclist traveling at 25 km/hr turns sharply to the left while continuing to move 25 km/hr. This means the forces involved are_____________________.

• Balanced, because the cyclist's speed did not change.
• Balanced, because he was still moving forward.
• Unbalanced, because it's the same bicycle.
• Unbalanced, because his direction changed.
