Kinematics

Water, wind, and pressure

670,616,629.2 miles per hour = 1.07925285 × 109 kph.

At top speed, an Italian greyhound can run up to 40 kph.

Yes, it does. Kinetic energy is energy in motion. If you have a waterfall, the energy

within it is constantly being moved. If it were perhaps a waterfall that was frozen

over, then it would not have kinetic energy; it would have potential energy.

Relative to the pool at the bottom, the water at the top has potential energy until

it reaches the edge. After it spills over, each kilogram of water loses 9.8 joules of

potential energy and gains 9.8 joules of kinetic energy for every meter it falls.

When it reaches the bottom, all of the potential energy it had at the top has been

converted to kinetic energy.

Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.

KE = (1/2)mass * velocity squared

KE = 1/2(100 kg)(3 m/s)2

= 450 Joules

1. By increasing mass. 2. By increasing velocity.

In a nuclear power plant, nuclear energy is used to produce heat through nuclear reactions. This heat is then used to produce steam, which drives a turbine to generate kinetic energy in the form of mechanical motion. The kinetic energy is ultimately transformed into electrical energy through a generator.

The unit m3s-1 can represent a multitude of things, depending upon the context.

It is most likely to represent the rate of change of volume, with respect to (wrt) time:

dV

dt

This is commonly a feature of problems in which a container is being filled at a certain rate (in m3s-1). The volume at any particular moment in time, V will simply be the integral of dv/dt, wrt time, after setting an additional constant such that V(t=k) generates the volume known for a specific time t=k.

Additionally, in a purely mathematical sense, it is possible to represent the force exerted in an area throughout a period of time, per unit mass, using this unit.

This (fictional) measure, with expression FAt/m [F=force(N), A=area(m^2), t=time(s), m=mass(kg)] arises, as 1N=1kgms-2, and so:

FAt/m -> kgms-2m2s kg-1 = kg0m3s-1 = m3s-1

This expression is also equivalent to moment in an area, per unit mass (pA/m) or simply velocity in an area (Av).

Any equation involving a product of length cubed and the reciprocal of time, with any additional units cancelling will also result in this unit, although most of these have no present applications in the field of physics.

315 km per hour = 195.7319 mph

The conversion of potential energy to kinetic energy follows "The Law of Conservation of Energy."
Energy cannot be created or destroyed. In a closed system it just changes form.
The total amount of energy in the universe does not increase nor decrease. It only changes forms.
So, if before big bang the universe was pure kinetic, it is now mostly potential. How much further can the energy disperse before gravity pulls it all back together into another big bang? just kidding...

If the force is not greater than the weight of the bale, the bale will not move.

1mi = 1.60km

253km/h x 1mi/1.60km = 127mi/h (rounded to three significant figures)

When the water is heated, its molecules get additional kinetic energy due to it. This results in their increased velocity. As their kinetic energy gets increased, they try to overcome the force of attraction between themselves and eventually water changes into water vapour.

1.34 miles

it means the object is moving at a constant speed

The maximum potential energy is at the top of each swing and is at its minimum at the bottom of the swing when it is perpendicular to a horizontal surface. The maximum kinetic energy is at the bottom of the swing, and is at its minimum at the top of each swing.

Please refer to the related link below for an illustration.

When the object is moved, even a tiny bit.

Another name for heat energy is Thermal energy.

KE = 0.5 x m x v2, where m is mass in kg, and v is speed in m/s.

you can do vertical graphs or data's it can be both ways

The rate of change in velocity is known as acceleration.

If you were going 70 mph for 190 miles on a straight road, with no stopping, traffic lights etc (which is almost impossible to avoid, especially for 190 miles), it would take approximately 2.7 hrs. Remember: this is on a straight road, no stopping, no traffic lights, no traffic and nothing to stop you. This is also counting on not stopping for extra fuel.

The "m" in kinetic energy stands for mass. It represents the mass of the object in motion and is part of the equation for kinetic energy: KE = 1/2 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity.

To find force using kinetic energy and distance, you need more information. You also need the time taken to cover the distance or the speed at which the object is moving. With this additional information, you can apply the work-energy principle, which relates the work done on an object to its change in kinetic energy to calculate the force.
