Yes, the Earth can push an object forward with a reaction force. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When an object exerts a force on Earth, Earth also exerts an equal force back on the object, causing it to move forward.
False. Earth won't push an object forward with a reaction force. It is a contravercy for the
gravitational force's laws.
The object is the fan and the reaction force is the air being pushed forward by the fan blades as they spin.
The action force is the gravitational pull of Earth on the object. The reaction force is the object's gravitational pull on Earth. According to Newton's third law, these forces are equal in magnitude and opposite in direction.
When you throw a heavy object forward, according to Newton's third law of motion, there is an equal and opposite reaction pushing you backward. This reaction is due to the force that you apply to the heavy object causing an equal reaction force in the opposite direction, leading to you falling back.
No, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the force exerted by the object on the Earth is equal in magnitude to the force exerted by the Earth on the object.
The name often given to the force exerted by the first object on a second object is the action force.
