Newton's First Law: The person is at rest while she (I'll pretend it's a girl) is on the ground because no net force is acting on her. Then she is thrown in the air by the force of those throwing her- why does she come down? If we assumed that there was no forces acting on her, she would continue rising forever, but since she falls, there must be a force which causes her motion to change (i.e. to slow down and then reverse direction). That force is gravity. Once on the ground again, she is no longer in motion because the downward pull of gravity is balanced by the upward normal force of the ground, and the net effect is zero force.
Newton's Second Law: When in the air, the girl is moving initially with upward velocity, but she slows down and then starts to fall. She must be experiencing a downward force, which again is the force of gravity. You know this because she is accelerating downward, so then you can conclude that gravity is acting in a downward direction.
Newton's third law: Ask the throwers- do they feel anything when they throw the girl in the air? They definitely feel pressure on their arms/hands as they throw her upward, because as they exert and upward force on her, she exerts a downward force on them equal in magnitude. The harder they throw her, the more the force they feel on themselves.

Because they don't have a choice.
Newton's laws of motion is used to describe motion. There are three laws that were compiled by Issac Newton, who was a mathematician.
Generally, rotation is the term for motion in a circular manner around a fixed line (the axis).Although the term "revolution" also refers to cyclic motion, it often refers to motion around an object or other fixed point. In astronomy, revolving is used for either circular or elliptical motion of satellites, while rotating refers to the spinning of a satellite such as a planet or moon.
The "pen at rest or in motion" is a part of a physics lesson used to teach Newton's Laws of Motion. It's used as an example for force, motion, and energy. A pen is in motion during active writing. Otherwise, the pen is at rest when not being used.
Newton's second law can be used to describe what we commonly know as weight. Weight is technically the force of gravity acting on our mass. Our weight, in Newtons, is equal to our mass times the acceleration due to gravity acting upon us on Earth's surface.
The term kinetics is a word that is used to describe the motion of particles or objects in motion.These include projectiles, how particles move, and Newton's Laws of Motion.
Newton's First law of motion states that everybody continues or tends to be in its state of rest, or of uniform motion, unless it is compelled to change that state by force impressed on it.

Lots of ways. For example, the momentum of satellite + meteor before the impact, is the same after the impact.
newtons laws are contributed by while the foot ball is in the air inertia acts on it.
The most used law of motion is F=ma, the 2nd law of motion.
Newtons is a unit of measuring force and is not to be confused with measuring mass. Another unit of measuring force is pounds. Newtons are often used as they are the SI unit of force.

All of them.

Cheerleading is used in a number of ways. It is used in many high schools for athletics, school spirit, and support to football teams. Cheerleading is also used this way through college and professional sports teams.
