velocity

what forces are active if a sky diver is falling at constant velocity

both air resistance and gravity are present and equal

if the same sky diver is in free fall what forces are present

only gravity acts on the diver, causing acceleration downward.

what forces are acting on a static hanging block

The forces acting on a static hanging block are tension in the support string and gravity acting downwards, which are balanced.

what forces are acting on a block accelerating up

The forces acting on a block accelerating upward include tension in the supporting string acting upward and gravity acting downward. The net force is upward, resulting in acceleration.

state nutens first law

An object at rest stays at rest, and an object in motion stays in motion at constant velocity unless acted upon by a net external force.

state nutens second law

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as $F = ma$.

why would a ping pong ball accelerate at a higher rate than a golf ball at the same force

it has less mas
