Kinematics

No. Kinetic energy is 1/2 times mass times velocity squared - so as you can see, acceleration doesn't even enter the equation. If it accelerates, the speed will change, though, and so will its kinetic energy.

Ipsa Raman is a fictional character from the TV series 'The Good Fight'. She is a young lawyer who joins the firm at the beginning of the second season and quickly becomes a central character in the show. Ipsa is known for her intelligence, confidence, and sharp wit.

Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.

215 mph is equivalent to approximately 346 km/h or 94.7 m/s. This speed is extremely fast and typically associated with high-performance vehicles like sports cars or racing cars.

Derivitives of a velocity : time graph are acceleration and distance travelled.

Acceleration = velocity change / time ( slope of the graph )

a = (v - u) / t

Distance travelled = average velocity between two time values * time (area under the graph)

s = ((v - u) / 2) * t

The speed of sound is approximately 767 mph, so any speed faster than that would break the sound barrier. Typically, speeds exceeding around 760-770 mph are considered supersonic.

White exhaust usually means that there is water in the combustion chamber and there is a crack somewhere. Pull out the dipstick and see if the oil is a milky white. If it is then you have either a cracked head or a cracked block. Heads cam be replaced somewhat affordable by a reputable mechanic, cracked block the engine is toast needs to be replaced.

Yes. For the object not to move, two conditions must be satisfied: (1) The vector sum of forces must be zero, and (2) The vector sum of torques must be zero.

Do some reading on torque, for more information.

Rocket ships can travel at speeds ranging from 25,000 to 36,000 miles per hour (40,000 to 58,000 kilometers per hour) depending on the mission and type of rocket.

A rock on top of a hill has potential energy, not kinetic energy.

If it starts rolling down the hill then the potential energy transforms to kinetic energy.

120 km/h = about 74 (74.5645431) mph.

In positive acceleration, the final velocity is greater than the initial velocity. This is because acceleration is the rate of change of velocity, so as time progresses, the velocity increases due to the acceleration.

Yes, it is possible. For example, if a particle moves back and forth between two points with different speeds, such that the time spent at each point is unequal, the average speed would not be zero even though the particle's speed is zero at each point.

A kicked football has, of course, kinetic energy. As it moves up, its vertical movement provides potential energy. Until it goes up to its maximum displacement from the ground, its potential energy is at 100% while the kinetic energy doesn't exist. As the football moves back down, its potential energy is decreasing, but kinetic energy is increasing because there's movement in the football

1 mile = 1.6 km

Convert miles to kilometers by multiplying miles x 1.6km/mi.

30mi x 1.6km/mi = 48km

30mi/h = 48km/h

30mi/h is less than 60km/h.

Radiation is a form of energy that includes both kinetic and electromagnetic energy. Kinetic energy refers to the energy of moving particles in radiation, such as in the case of alpha or beta particles. Electromagnetic energy refers to the energy carried by waves, like gamma rays.

The average kinetic energy of particles in a substance is directly related to its temperature. Understanding this average kinetic energy helps us predict how the substance will behave in various conditions, such as changes in temperature or phase transitions. This knowledge is crucial in fields like thermodynamics and materials science.

No, a hammer held above a nail has potential energy due to its position relative to the nail. Potential energy is energy that an object has due to its position or state, whereas kinetic energy is energy of motion.

20 km per hour is approximately equal to 12.4 miles per hour.

Gaining kinetic energy 'E' amounts to saying that the momentum of an object increases.

E = p^2 / 2m

where p is momentum and m is mass. (Momentum is just mass times speed.)

So, to increase the speed the kinetic energy has to change. In other words, if you set the kinetic energy to any value you like and keep it constant, there won't be a speed up.

What is the change in kinetic energy? You can just as well ask what is the change in momentum. Physicists have chosen the latter question and call the change in momentum 'the force'.

F = dp / dt

where F is force and d/dt means derivation with respect to time.

It is the pushing force acting on objects that makes them gain speed. Kinetic energy is usually something that you calculate at the end when you have found out what the forces in your problem are and what the momentum is as a function of time.

5 km per second = 18,000 km/h or 11,184.7 miles per hour.

100 kilometers per hour equates to 62.14 MPH

An electron can reach zero velocity by experiencing a slowing force, such as friction, that opposes its motion. Alternatively, if an equal and opposite force acts on the electron to stop its movement, it can also reach zero velocity.
