Every object in a state of uniform motion
tends to remain in the state of motion
unless an external force is applied to it
All objects resist changes in there state of motion In the absence of an
unbalanced force, an object in motion will maintain this state of motion
An example of this law would be a skater rolling down the sidewalk and
being stopped by a crumpled piece of paper, because the skater
continues its motion with the same speed in the same direction until the
crumpled piece of paper (Unbalanced force) stops the skater
Another example would be a car running into a brick wall,
because the car continues its motion with the same speed
in the same direction, until the brick wall (Unbalanced
forced) stops the car.
Newton's first law relates to Football, because the football
itself is at object at rest. Until a player kicks the ball
(external unbalanced force acts on it). Acting as an external
unbalanced force when the player kicks the football.
Newton's First Law of Motion
Newton's Second Law of Motion
Acceleration is produced when a force acts on a mass. The
greater the mass (of the object being accelerated) the greater the
amount of force needed (to accelerate the object)
Heavier objects require more force to move the same distance as lighter
objects
An example of this law would be a person trying to kick a wall. The
wall acts as the heavier object which requires more force to move to
move the same distance as a lighter object. Such as a person kicking a
soccer ball. It would take less force to kick the soccer ball, because it is
a lighter object therefore it would take less amount of force.
Another example of Newton's second law. Is a person trying to push
their car to a location, because they ran out of gas. Since the car is a
heavy object it will take the person. A lot more force to pull a car
than it would a much lighter object.
Newton's Second Law relates to Hockey. When two players collide
Newton's Second law helps to calculate what the final veloctiy of the
two players will be. For example a very large player striking a small
player at rest will create a large velocity in the small player, because a
force such as the body check of the bigger player was applied to him.
Newton's Third Law of Motion
For every action there is an equal and opposite reaction
For every force there is a reaction force that is equal in size but
opposite in direction. Whenever an object pushes another object it
gets it gets pushed backed in the opposite direction equally hard.
An example of this law would be a rocket. The rocket's
action is to push down on the ground with the force of its
powerful engines, and the reaction is that the ground
pushes the rocket upward with an equal force.
Another example of Newton's Third law would be what
occurs when we step off of a boat onto the bank of a
lake. As you move toward the direction of the shore, the
boat tends to move in the opposite direction.
Newton's Third Law relates to Hockey. When the larger player
experiences a force from the smaller player pushing back on the
bigger player. The bigger player soon gets slowed down . And
the collision between both players remains conserved.
