 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mr. Hardens class decides to perform an experiment to determine how long it takes different objects to hit the floor when dropped from a desk. The class dropped 3 balls from a desk, one weighing 2 lbs, one weighing 4 lbs and 6 lbs. It took them all the same amount of time to hit the floor. After evaluation these results, you predict that a 10 lb ball will take
 A more time to hit the floor B less time to hit the floor C about the same amount of time to hit the floor D an unknown amount of time before hitting
Explanation:

Detailed explanation-1: -A ball develops a certain amount of acceleration after being hit. The acceleration with which the ball moves is directly proportional to the force applied to it. This means that the harder you hit the ball, the faster it will move, thereby demonstrating Newton’s second law of motion in daily life.

Detailed explanation-2: -Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

Detailed explanation-3: -Newton’s second law states that the net force, or the vector sum of all the forces acting on an object, equals the mass times the acceleration.
