Hello there! When a ball is in motion, one should consider:
• The velocity
Velocity is denoted as speed in a given direction. This should be considered in terms of experiments and tests to identify the ball’s acceleration and where it is going.
• Isaac Newton’s 1st Law of Motion
Isaac Newton’s first law of motion states that an object in motion remains in motion unless acted upon by an unbalanced force. This is important to consider because an observation is noted that an unbalanced force acted on the ball to make it move.
• The ball’s mass
It is important to consider the ball’s mass while it is in motion. This is important because the mass of the ball can affect the amount of friction applied to it by a balanced force, rendering either a long or short amount of time before the ball releases kinetic energy.
Hope this helps!
