true.due to newton's 3rd law when the gases push against d ground,the force exerted makes it move ahead.
Forces that are equal in magnitude but opposite in direction. For example, if you push against a brick wall and it doesn't move or become deformed, then the brick wall is exerting an equal force against you.
Forces always come in pairs. If there is a force of object A against object B, then there will also be a force of object B against object A. Which of the two should be called "action" and which "reaction" is sometimes an arbitrary decision.
The prefix "counter-" typically means against, opposite, or in response to something. It is often used to indicate opposition or reversal of a particular action or idea.
In the opposite direction, and on the other object. In this case, the chair pushes upward against the person.
The answer is reaction. A simple example is you standing on the ground. You are not moving or accelerating (in our reference frame). You are pushing down against the ground with a force (the action) equal to your weight. The ground pushes back up (opposite direction) with an equal force (the reaction force).
It is an informal statement of Newton's Third Law of motion. It means that if an object "A" pushes against an object "B", then object "B" will push back against object "A". This second force will be the same magnitude as the first, but in an opposite direction.
An example of such a force is friction, but a term for forces that act against motion are decelerative forces.Newton's Third Law states that for every action, there is an equal and opposite reaction. However, these can be in any direction and may or may not influence an object in motion.
Reaction
When a bullet is fired from a gun, it creates a sudden release of gases that exert a force on the gun's barrel and action system. This force, known as recoil, causes the gun to jerk backward in the opposite direction of the bullet's motion. The jerk is a result of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
-- The force of gravity of your bottom against the rock, in the downward direction. -- The 'reaction' force of the rock against your bottom, in the upward direction. Since the forces are equal in magnitude and opposite in direction, their vector sum is zero. Some would describe this situation as "The forces on your bottom are balanced." In any case, the 'net' force on your bottom is zero, and your bottom therefore does not accelerate.
they do! for every action is an equal and opposite reaction. To propel a rocket into orbit an equal amount of force is expelled in the opposite direction. This is often dissipated into the atmosphere in the form of heat.
When an object is moving in a particular direction, air resistance will be acting on the object in the opposite direction to the direction of travel.
