Question
Identify which of the following have balanced forces acting on them. Shoes resting on a shoe rackA car turning a corner A skateboarder speeding up as they ride down a hillA car travelling at a constant speed
Solution
-
Shoes resting on a shoe rack: Yes, the forces are balanced. The force of gravity pulling the shoes down is balanced by the normal force of the shoe rack pushing up.
-
A car turning a corner: No, the forces are not balanced. When a car turns a corner, there is an unbalanced force acting towards the center of the circle that the car is moving in (centripetal force). This unbalanced force causes the car to change direction.
-
A skateboarder speeding up as they ride down a hill: No, the forces are not balanced. The force of gravity pulling the skateboarder down the hill is greater than the force of friction and air resistance opposing the motion, causing the skateboarder to speed up.
-
A car travelling at a constant speed: Yes, the forces are balanced. The force propelling the car forward (from the engine) is balanced by the forces opposing the motion (friction and air resistance).
