Questions On Momentum

Newton 's three laws of motion play a huge role in our everyday life; from driving down the road and catching a baseball. Newton’s laws help us fully understand gravity, motion, and force in three easy-to-understand laws.

The ball now has kinetic energy. Kinetic energy like momentum in that it comes from the mass of the object and its velocity. Kinetic energy was transferred from the plunger to the ball just like momentum was but only if the collision was elastic. During and elastic collision kinetic energy is conserved. The balls kinetic energy is half of its momentum squared. This means the balls momentum is its mass multiplied by velocity, and then it is squared and divided by two. If the velocity or speed of the ball is reduced by one half then the overall kinetic energy is reduced by a factor of four (Kirkpatrick and Wheeler p.106)

Newton’s first law of motion states that an object in motion will remain in motion, while an object at rest will remain at rest unless acted upon by another force. This seems to be true with humans as well because it is more likely that a person will remain active in their later years if they remain to be active through the critical time of their late teens and twenties. Because a major portion of this age category is in college, it is crucial for universities and community colleges to provide physical education to help students achieve and maintain a standard level of physical and mental fitness outside and inside the classroom.

Newton’s 3 Laws of Motion are some of the most important scientific discoveries of all time. No matter where you are or what you are doing, you can always see them. Whether you are scuba diving or free falling, these Laws apply to you and could help you get a better understanding of most things. One place where you can see Newton’s 3 Laws of Motion in action is the basketball court.

Momentum is the mass of an object times it’s velocity. The velocity of an object would be it’s rate and change of direction. A collision occurs when two or more objects collide with each other. This causes the kinetic energy, the energy of motion, to be transferred

Newton’s laws of motion are three physical laws that describe the connection between a body and the different forces acting upon it, as well as its motion in response to those forces. Isaac Newton developed Galileo’s ideas further and developed three law of motions. Newton’s First Law of Motion states that an object at rest with remain this way unless if it affected by a force. Also if an object that is moving will continue at the same speed as well as the same direction until an unbalanced force acts upon it. An example of unbalance force is when a scooter is being driven, the friction and air resistance is going at it, the weight of the scooter is keeping the weight on the ground, the reaction force is going up and the thrust of the scooter going forward. The force’s tendency to resist any change in motion is called an object’s inertia. Newton’s Second Law of Motion states that an object will keep on accelerating in the direction of an unbalance force acting upon it. The mass of the object and the size of the force acting depends upon the size of the acceleration., F_net=m x a, is the formula to work out the total amount of force acting upon an object. This formula can be

Let the mass of the fired bullet be Mb. It is fired at an initial velocity of v. The momentum

Kinetic energy is the energy that a body possesses by virtue of being in motion.

We had some error in our experiment, with human error launching the cart and we did not record the carts bouncing back from the wall. Our data is consistent and we can observe the difference between each table. We were able to see the cart’s total momentum equal around the same after the collision, unless it was an inelastic collision or if we added the 500g the velocity would be halved.The max force that occurs during a collision is a function of the change in velocity over a change of time. The shorter the time span, the larger the force must be. However it did not change the momentum, because the according the law of conservation momentum principle the energy is conserved within the system. If we would have recorded D3 when the cart bounced off the wall after collision we would have an even more accurate account of the law of conservation momentum

Work out the following problems. Be sure to show your work in detail. See the hand out uploaded for examples of how the problems should be solved and presented.

1. The force of the window on the bug because the bug is just flying, but the force of the window at a given speed is much greater creating the force to splatter the bug.

First topic (Momentum in pitch) - The momentum of the ball is ultimately one of the deciding factors in distance traveled. When pitched, the ball will have momentum towards the catcher. The bat at this point would have no momentum as it is at rest. When the ball is hit, the direction of its momentum changes towards the pitcher, but in doing so it must maintain the total momentum of the system, so

(Melvin, Mangonel - “Physics of Catapults”) The speed and distance of the projectile depended on how much force the catapult applied to the projectile, and the momentum depended on the mass and the velocity of the projectile (dead diseased cow, or flaming

Another basic element of basketball is that of passing the ball to another teammate. The physics involved in this process are velocity, momentum, and impulse. The ball has a mass and when it is thrown a velocity of the ball in created. From these two parts momentum is derived, P=mv (Kirkpatrick Wheeler 106). While playing basketball it may be to your advantage to increase or decrease the momentum of the ball when passing to a teammate depending upon the situation.

HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.
