Momentum

One pair is greater than the other due to the difference in mass of those involved in the action-reaction pair.

They are equal in magnitude and opposite in direction since every action has an opposite reaction per Newton's Third Law of Motion.

The reaction force is slightly less strong in the opposite direction to conserve momentum and allow for the exchange between the bodies without violation.

It depends on the relative motion of the station and astronaut with respect to Earth.

Speed stays the same despite changes in altitude; the system's preservation of total mechanical energy dictates constant velocity increase potential decreases kinetic counterpart.

Reducing slows down the satellite and it falls back towards the planet due to a lower possible escape velocity.

Increasing results in higher speed because it is further away from the gravitational source, thus requiring faster travel to overcome its weaker pull.

Satellite speed decreases with increased altitude due to an increase in radius, reducing the need for velocity to achieve the centripetal acceleration necessary to maintain orbit stability.

An external constant force acts only on glider A without interacting with B.

Glider A receives an impulse from an external source but transfers it completely to B.

Glider A accelerates due to its own propulsion mechanism affecting only itself.

Glider A exerts a force on B for time t, while simultaneously glider B exerts an equal force on A for time t.

It becomes zero.

It increases after collision.

It remains the same as before the collision.

It decreases after collision.

False

True

The total momentum remains constant.

The total momentum gradually decreases to zero.

The total momentum fluctuates unpredictably.

The total momentum increases over time.
