Kinematics

Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction.

Speed without reference to a direction is a scalar, a magnitude without direction.

They all have the same gravitational potential energies.

Kinetic energy is equal to one half the mass times the velocity squared. Thus in this case it would be 0.5 * 1600kg * 12.52 (m/s)2

= 800*156.25 kg m2/s2

= 125000 kg m2/s2

= 125000 N m

= 125000 J

= 125 kJ

The braking of a vehicle involves a serious of energy transformations. The application of hydraulic pressure onto the caliper piston pushes the friction material against the rotors. In simplest terms the vehicle's kinetic energy is being converted into intense heat generated by the brake pads and rotors. In turn the vehicle slows down and can ultimately stop.

Length is the measurement of the extent of an object along its greatest dimension. It typically refers to the longest side or distance from one point to another on an object.

Momentum (p) is the product of mass (m) and velocity (v). Plug your known values into p = m x v and you've got p = 910 kg x 13.3 m/sec The calculator says 12,103 kg - m/s which is 12,103 Newton seconds. Note: Momentum usually refers to linear momentum, or movement in a line. Additionally, momentum is a vector quantity. It has direction associated with it, and we've left it off the above calculations because it (the direction) wasn't specified.

The full form of the word physics is physics. It does kind of sound like it derives from the word physical science or physiology or something but it doesn't.

Stored energy refers to energy that is stored in an object or system and is potential energy waiting to be released, such as in a battery or a compressed spring. Energy in motion, also known as kinetic energy, is the energy an object possesses due to its motion, such as a moving car or a swinging pendulum.

parameters given are :

mass(m)=20kg

height(h)=30m

acceleration due to gravity(g)=9.8m/s squared

But K.E=1/2MV`2 = mgh = 20x9.8x30 =5880 joules or 5.88 kilo-joules.

potential energy = m*g*h m=62kg g=9.81 m/s^2 h=410m multiply all those together and you get 249,370 Joules.

Increasing mass increases kinetic energy because kinetic energy is directly proportional to mass. This means that as mass increases, the kinetic energy of an object will also increase, assuming the velocity remains constant.

I'm not sure if this helps in any way, but i do know that with a pendulum, the height it goes on one side is the exact height it goes on the other so if you held it up say 30cm on one side and let it swing it would reach 30cm on the other!!!!

i thought that was pretty cool anyways- sorry i couldn't help further xxx :)

The energy possessed by a body in motion is kinetic energy. It is the energy associated with the movement of an object.

At halfway, the forces are equal. At three quarters of the way down, it will have three times the kinetic energy as it does potential (having travelled three times the distance than is left). So at 7.75m into the fall it's kinetic energy will be triple it's potential energy.

First you have to resolve all forces into vertical and horizontal. If it on a slope take the reaction force as vertical and the slope as horizontal. Then equate the opposite forces, for example the friction and the driving force, and use maths to figure out the resultant.

Kinetic Energy products designed by Wilma van Boxtel can be purchased on the designer's official website or through select retailers that carry her collections. Additionally, they may also be available at specific art or design exhibitions where her work is featured.

A. A rubber bend of length .7m is stretched to connect to points A and B. A tension force of 40 N is thereby developed in the band. A 20-N weight is then attached to the band at C. Find the distance a that point C moves downward if the 20-N weight is constrained to move vertically downward along a frictionless rod.

[Hint If you consider part of the band, the "spring constant" for it will be greater than that of the whole band]

A change in velocity with respect to time is known as acceleration. It measures how quickly an object's velocity is changing over time, whether it is speeding up, slowing down, or changing direction. Acceleration is a vector quantity, meaning it has both magnitude and direction.

A glancing collision is a type of impact between two objects where they come into contact at an angle rather than head-on. This can result in the objects deflecting or sliding off each other rather than directly impacting. Glancing collisions can affect the direction and outcomes of the objects' motion after the collision.

As in automobile tires, the purpose of the tread is to increase traction (friction). They increase the surface area of shoe-to-ground contact.. Further, the tread forces softer ground to mold to its shape, allowing more lateral force to be applied to each step. All this increases the traction between your shoes and the ground and allows better control of movement (allows more applied energy to each step with less slippage).

That depends how large the piece of marble is, and how fast each is moving.

If you take a regulation basketball and a basketball made out of marble, and throw both of them

with the same speed, the marble has more kinetic energy.

But if your throw is any good, they both follow the same arc, and they both sink, for a total

of 4 points.

Velocity has a greater impact on kinetic energy than mass. This is because kinetic energy is proportional to the square of the velocity, while it is directly proportional to mass. Therefore, doubling the velocity will quadruple the kinetic energy, while doubling the mass will only double the kinetic energy.
