How does a carbuerator work?
Basically, it mixes gas and air and pushes into the cylinders to ingnite and cause an explosion pushing the pistons down, and turning the crankshaft.
When a boy lands on a trampoline he pushes the trampoline what is the reaction force?
The reaction force when a boy lands on a trampoline and pushes it is the trampoline pushing back against the boy with an equal and opposite force. This is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
What action and reaction are present when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
What are examples newtons third law?

When a boy pushes down on an diving board what is the reaction force?
The reaction force when a boy pushes down on a diving board is the diving board pushing up on the boy with an equal force. This is in accordance with Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
What muscle moves down when you inhale and up when you exhale?
During passive breathing the diaphragm moves down for inhalation this pushes the organs of the abdomen down and so pushes the rectus abdominus out, this is why you see your abdomen moving. To assist exhalation the rectus abbominus then contracts pushing the organs back in and so pushing hte diaphrag pack up.
What action forces and reaction forces are present when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
When a boy lands on a trampoline he pushes down on the trampoline what is the reaction force?
The reaction force when a boy lands on a trampoline and pushes down is the trampoline pushing up on the boy. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Why do paper helicopters flutter?
Paper helicopters flutter because the air gets under them and pushes them up against the natural gravity that is pushing them down. If made right these can flutter and fly quite a distance before finally coming down.
