Consider the situation below which of these is the best example of Newton's first law a Tom uses a cane to walk across the road b you go down a steep hill and a sled and it feels like your stomach is going into your throat see a bird takes flight from the ground or d a tennis player through the tennis ball into the air force a and the ball falls to the ground

The best example of Newton's first law in this situation is:

a) A tennis player throws the tennis ball into the air (force), and the ball falls to the ground.

Newton's first law states that an object at rest will stay at rest, and an object in motion will continue in motion with the same speed and direction unless acted upon by an external force. In this example, the tennis player applies a force to throw the ball into the air. Once the ball is in motion, it will continue moving until the force of gravity acts upon it, causing it to fall to the ground.
