Kinematics

The information given by the slope of ("on") a distance-time graph is the SPEED. The size ("magnitude") of the slope is the size of the speed and the units of the distance axis are divided by the units on the time axis to give the units of the speed ... so if your distance is in miles and time is in hours then your speed will be in miles per ("divided by") hours (mph)... but if distance is in metres and time is in seconds then the speed is in metre per second (m/s).

The formula as usually written is.............

KE =1/2 mass * velocity squared

KE = 1/2mV^2

but you can rewrite this as..........

KE = mV^2/2

which answers your question by saying........

mass and velocity squared are divided by 2 to get kinetic energy

1 Kilometer per Hour = 0.621371192237334 Miles per Hour 235 Kilometers per Hour = 146.02223017577347 Miles per Hour

After water or anything else falls to the ground it has no potential energy anymore.

When mas is elevated it has potential energy. When it falls, the potential is converted to kinetic energy. That energy is then converted to light, heat, sound or compression of the object on to which the mass fell. But then the mass has no more potential energy.

Kinetic energy.

Specifically

K.E. = ½mv²

where

K.E. is kinetic energy

m is mass

v is velocity

Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.

The position at time t (and therefore the height of the p-t graph) will be the area under the v-t curve between time 0 and t.

The condition for an object to stay at rest or if moving, moving at a constant

velocity is that the sum of forces acting on the object be zero or that no force

acts on the object.

It represents that the object is remaining at a fixed distance. Typically that means it is not moving.

75 mph is equal to 120.7 kilometers per hour

The Spine-tailed Swift is the fastest flying bird. This Asian bird has been recorded at speeds up to 106 miles per hour. Note: Falcons have been clocked at higher speeds when diving from high altitudes but never in level flight.

|v| = sqrt( 2 * KE / m ), with |v| being speed.

38 miles per hour is 61.16 kilometers per hour.

The knot is a unit of speed equal to one nautical mile per hour, approximately 1.151 mph. Thus, 429 knots is 429 x 1.151 = 493.779 mph

As the kinetic energy of matter is increased, the temperature increases and phase changes from solid to liquid or liquid to gas occur. If pressure is low enough, sublimation could occur.

The kinetic energy of the ball is converted into elastic energy through deformation (I assume we are not talking about steel balls). The elastic energy is then released, pushing the ball back up. Some energy is lost in the ball where it will cause heating, and some is probably lost to the floor, depending how elastic the floor is, so the rebound bounce won't reach the same height as the initial height, but total energy must be conserved.

Acceleration is negative.

In kilometers per hour, 133MPH is approximately 214.04KMPH.

There is a Reaction, called recall or kick.

That should read "recoil."

Kinetic energy is the sum of all the parts of momentum:

p=mv >function for momentum

∫ p=∫ mv.dv >integrate both sides with respect to velocity

∫ p=.5mv²=Ek >results in formula for kinetic energy

At 9 miles per hour you can run 6.75 miles in 45 minutes.
