Momentum

When a force is given to an object that can move or is moving, it changes the momentum. If the change in the momentum is faster, the force involved is greater. Momentum is calculated so that mass multiplied by velocity equals to momentum. If a car is driving at a fast speed, the more force and energy it contains. Safety features of a car are put in place so that they protect the occupants’ if a crash were…

Power Power is a relevant and one of the most important skill-related components of fitness to the performance of a javelin throw. Muscular power is the ability to combine strength and speed in an explosive action and this is shown in a javelin throw. There are two types of powers, speed-dominated power, which is power generated through a greater emphasis on speed and is essential in activities such as sprinting and throwing which javelin includes. As well as strength-dominated power, which is…

The experiment is an investigation about the Zeeman Effect in an atomic Cadmium lamp. The part of the spectrum observed will be the 645nm (red) emission line. Electrons occupy energy levels within an atom when a photon of energy hf is absorbed by an electron in the n=1 level and if the energy is such that the electron is excited and ascends to the n=2 level after some time the electron will then descend back to the n=1 level and a photon of hf will then be emitted again. Each atom has its own…

a greater angular velocity. Greater angular momentum means they have the potential to do more flips. The gymnast gains angular momentum by pushing off the surface at an angle. As mentioned earlier the Yurchenko vault has four opportunities to push off a surface. This means that it has four opportunities to increase angular…

overhead serve. Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. The amount of momentum used in an overhead serve will determine the force the ball will travel over the…

Tackling is an important aspect of the game. You have to tackle so that the opposing team does not catch the ball or score a touchdown. When a player is running down the field, it allows him to gain momentum. For the runner to be stopped, the tackler has to inflict and impulse with greater force. Newton’s three laws of motion are all taking affect when trying to tackle another player. Newton's first law tells us that an object either at motion or at rest tends to stay in that state of motion or…

The velocity of the rocket represents the distance the rocket gained over the amount of time it was in the air. The momentum represents how the mass of the rocket flew through the air per second. The height of the rocket represents how high the rocket flew with the data calculations from the most successful flight. The net force of the rocket represents both the thrust…

not working without the reinforcement. In this experiment, we focused on how the schedule of reinforcement made some effects to the response during reinforcement and extinction phase. The rate of the reinforcement is associated with the behavioral momentum theory which is the resistance to the change. Craig, Cunningham, & Shahan (2015) suggest that higher resistance to the effect of the extinction is associated with higher rate of the reinforcement…

In the video “The Five Levels of Management,” John Maxwell stated that the five levels of leadership are position, permission, lead by example, people development level, and the Pinnacle level. I thought he explained the five levels of management very well and in a way that is relatable. Anyone who has had a supervisor or has been a leader can relate to his analogies and experiences. I felt that I could put his words together with our text book and class lectures well. John stated that level…

This allows the ball to gain enough momentum to travel around a vertical loop without coming back down. While the ball rolls around the loop, it experiences a centripetal force, which is a force that pulls towards the center of the loop, making the ball travel in a curved path. After the inclined…
