Momentum

When we talk about momentum i always think about motion through mass and how momentum is key to movement as well.  To define momentum , All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much mass or stuff is moving and how fast the stuff is moving. Momentum depends upon the variables of mass and velocity In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. The picture that i have to present today is a picture of my friend when we were hitting on the courts.  If you watch you notice that momentum occurs when the force of the racket comes in contact with the tennis ball and all that force that was pushed through the racket is eventually on contact causes the force to transfer

Accelerating Forces

In my opinion when accelerating forces occur in front of me i think of the 2nd law of motion from Newton, out of the three laws created the 2nd one compares and contrast the most accurate about that situation.  To define the second law of motion from Sir Isaac it states "acceleration is directly proportional to the net force of an object, and that acceleration is inversely proportional to the mass of an object. The equation is Fnet=ma.  Giving us the equation to solve the acceleration of the specific force.  In this picture it shows a tennis ball rolling across the floor, notice this is a floor area that is not causing as much friction as many floors, this would allow a smoother surface and it will eventually accelerate throughout the duration it is rolling.

Newton's blogpost

When we talk about the newton's law of motion the first one is stated:  An object that is at rest will stay at rest unless an external force acts upon it.An object that is in motion will not change its velocity unless an external force acts upon it.  The second law is stated The relationship between an object's mass its acceleration and the applied force is F=ma.  Acceleration and the force are vectors in the law the direction of the force vector is the same as the direction of the acceleration vector.  Lastly the third law of motion states:  For every action  there is an equal and opposite reaction.  This helps us understand the concept of how balance occurs for the simple fact that opposite forces have to always be equal.  In this picture it shows the first law of newtons law of motion where this object is at rest, unless i move it or an outside, unbalance force acts upon it, the object will stay at rest

Projectile motion part: 3

SInce we are talking about projectile motion again we should always remind the fact that x-axis and y-axis are always in the relation of the motion.  We always need to understand how motion works due to gravity, and other factors that we always face in the world.  We also have to understand that the work we do we have to always find the Distance, Time, Acceleration, velocity, and original velocity for both the x and y axis because it helps us know the horizontal and vertical changes in motion.  In this picture my friend Marcel Chan is about to hit the tennis ball with topspin, when the ball is hit the ball's motion will be a parabolic motion and that shows a projectile motion and you will see increase in height or y-axis and the horizontal axis will move farther.
