3rd: For every action, there is an equal and opposite reaction. Conservation of Momentum: In an isolated system, (a system with no outside force acting upon it) then the total momentum will remain constant. Inertia: The tendency an object has to follow the same path all the time and not change its motion. Friction: Sliding Friction: the friction on an object while it is moving. Static Friction: Static Friction is the friction that acts on an object that is stationary.
Momentum Conservation Principle: The law of momentum conservation tells us that in the collision between 2 objects in an isolated system, the momentum of the two objects before the collision is the same to the momentum after the collision. This means that (2) the amount of momentum that object 2 gained is equal to the amount of momentum that object 1 lost. This statement tells us that the total momentum of colliding objects is conserved. This tells us that momentum is a unchanging value. The Logic Behind Momentum Conservation: In a collision between two objects, object 1 and object 2, the forces acting between the two objects are equal in magnitude but opposite and direction.
This force compresses the ball. The force that the ground exerts on the ball does work on the ball, since it is in the same direction as the displacement. The gravitational potential energy the ball has before it is dropped is converted into kinetic energy while the ball is falling and then into elastic potential energy as the force from the ground does work on the ball. But because the material the ball is made of is not perfectly elastic, friction converts some of the energy into thermal energy. The elastic potential energy stored in the ball when it has lost all its kinetic energy is converted back into kinetic and gravitational potential energy.
Va Vr. This means that the graph of my results should produce a straight-line graph as they are proportional (as shown in the diagram). This also means that the wooden block takes the same proportion of energy every time the ball hits the block The reason why I think that the rebound speed will be slower than the approaching speed is that some of the kinetic energy from the moving ball is converted to the form of heat and sound when it hits the block. The kinetic energy of the ball has not been destroyed only changed its form, as quoted in my background information. If an object of mass 'm' moves at speed 'v'.
The existence of the “sweet spot” is mainly because the vibrations do not agitate at that particular node. Impact on the first node will not excite the first mode, but will affect the second mode. Thus is true for the second node’s relationship with the first mode. Close to where the point of percussion occurs is the “sweet spot.” According to a study done by H. Brody at the Physics Department of the University of Pennsylvania, “A bat of mass M and with initial velocity zero can be treated as a free-body that is hit by a ball whose momentum changes due to the interaction.” At the time of percussion the bat will oscillate which indicates a transferal of kinetic energy into vibrational energy and some kinetic energy is lost. When all this occurs it is an extremely aggressive action.
The force can be the gravity. The kinetic energy will be the mass and velocity. The potential energy on the launch pad. Newton’s first law is about the state of motion of an object does not charge as long as the net force acting on the object is zero. His second law is about the acceleration of an object is equal to the net force acting on it divided by the object’s mass.
We can also obtain by using Newton's 2nd law how there is no acceleration on the falling object. We know that when there is a greater gravitational force moving on a falling object than a frictional force, that it is accelerating. However when both these forces equalise, a constant speed is present. Therefore the total net force on that object is 0. By using Newton's equation of Force = Mass X Acceleration, and inducing the fact that F = 0, and that mass can not equal zero, that the acceleration must also be zero.
K = ½mv2 where K = kinetic energy When you strike another ball with the cue ball it is almost a perfect elastic collision. An elastic collision is one in which total kinetic energy as well as total momentum are conserved within the system. This can be shown by the two basic equations; Conservation of Kinetic Energy: ½m1v1i2 + ½m2v2i2 = ½m1v1f2 + ½m2v2f2 Conservation of Momentum: m1v1i + m2v2i = m1v1f + m2v2f where m = mass of object v = velocity Since the cue ball has virtually the same mass as the other balls and the velocity of our second ball will always be zero, since we are striking a static ball with the cue ball. In addition this is considered a two- dimensional collision. From this we know that momentum is saved within the y component and within the x component.
Before I explain and talk about why a ball goes farther when hit with an aluminum bat, I would like to present and explain some vocabulary concept and words. A collision, transfers momentum or kinetic energy from one object to another object. There are two types of collisions, elastic collision and inelastic collision. An elastic collision is a collision that occurs when two objects bounce apart when they collide; the total kinetic energy in the system is the same before and after the collision. For example, elastic collision occurs when equally massive balls move in the same direction; in this case momentum is transferred from one ball to another ball.
Bernoulli’s Equation for real fluid The Bernoulli’s equation was mainly derived for ideal fluids i.e zero viscous fluids hence they are frictionless. But all the fluids are real and has some viscosity and hence offer resistance to flow. When the fluid is flowing there will always be some losses across the sections and Bernoulli’s equation considers all the losses. P_1/ρg+ (V_1^2)/2g+ Z_1= P_2/ρg+ (V_2^2)/2g+ Z_2+ h_l…………………………… Eq(7) Where h_l = Head loss across the
