According to Newton's First Law of Motion . every action has an equal and opposite reaction
objects in motion will keep moving unless acted upon by force
objects at rest can start moving on their own
objects in motion stop moving once force is removed

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
