Why do many people push a bus in the same direction to start it?
- To apply parallel forces which are easier to coordinate (correct)
- To test their combined strength
- To create opposing forces for better traction
- To demonstrate teamwork

What is the advantage of applying parallel forces to an object?
- They are easier to coordinate and produce a combined effect (correct)
- They cancel each other out
- They cause the object to move in the opposite direction
- They increase friction

Study Notes
Forces and Movement
- Many people push a bus in the same direction to start it because it requires a large amount of force to overcome its inertia.
- Forces that are parallel to each other are called parallel forces.
- The advantage of applying parallel forces to an object is that they combine to produce a greater total force, making it easier to move or start the object.
