Distinguish between apparent weightlessness and true weightlessness?
Apparent weightlessness occurs when an object is in free fall, making it feel weightless due to the absence of support forces. True weightlessness occurs when an object is at a point in space where the gravitational pull is negligible, resulting in a complete absence of gravitational forces acting on the object.
What happens whenever an object pushes another object?
When an object pushes another object, it applies a force that causes the second object to either move or change direction depending on the magnitude and direction of the force applied. This interaction follows Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
Are action reaction forces always the same force but in different directions?
Yes, action and reaction forces are equal in magnitude but opposite in direction according to Newton's third law of motion. This means that when one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
What does action and reaction mean?
Action and reaction refer to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that the force one object applies to another will result in an equal force applied back on the first object. It explains how objects interact with each other in the physical world.
An object with no apparent weight experiences BLANK?
An object with no apparent weight experiences weightlessness.
Is weightlessness a noun?
Yes, the word 'weightlessness' is a noun, a word for a state in which an object has no actual weight.

What is an action force?
Action Force is a force that exerts a force on another object. It often comes in pairs with the Reaction Force, forming an action-reaction pairs. The action-reaction force is Newton's third law of motion.Newton's third law of motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.what they said

An object with no apparent weight experiences weightlessness.
What does action and reaction forces mean in physics?
Action and reaction forces refer to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that when one object applies a force on another object, the second object will exert an equal force back onto the first object. These forces act on different objects and not on the same object.
What is the term for the force exerted on an objects by another object?
reaction
How is vertical acceleration linked to the sensation of weightlessness?
Vertical acceleration is linked to the sensation of weightlessness because when an object is accelerating upwards at the same rate as gravity, it creates a feeling of weightlessness. This is because the object and the person inside it are falling at the same rate, cancelling out the effects of gravity and making it feel like there is no weight.
For every action is there an equal and opposite reaction?
This statement is derived from Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction. This principle applies to forces in physics.
How does weightlessness occur?
When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
