Is determined by mass and velocity of an object?

Momentum and kinetic energy are determined by the mass and velocity of an object.

Momentum = m• v, where m is mass in kg and v is velocity in m/s.

KE = 1/2mv2, where m is mass in kg and v is velocity in m/s.

What will be the kinetic energy of the ram of a pile driver when it suddenly undergoes a 10-kJ decrease in potential energy?

10-kj will be added to the Kinetic Energy. Remember the law of conservation of energy. E=PE+KE. and Efinal = Einitial.

How fast is 100-120kph in miles per hour?

100-120 kph is equivalent to approximately 62-75 mph.

Can you get a ticket for going 60 mph in a 75 mph in AZ?

Yes, in Arizona, exceeding the posted speed limit can result in a ticket regardless of how fast you are going compared to the limit. It is important to always follow the posted speed limits to avoid any potential fines or penalties.

What is 104 mph in kmh?

167.371776 Km/h

Ill tell you a cool trick go to google.com and type

"104 mph to kph" and it will tell you so you can use it again.

Would you be consuming more fuel when driving at 120 kph 130 kph or stopping and starting?

You would consume more fuel when driving at 130 kph compared to 120 kph due to increased air resistance. Stopping and starting frequently in city driving consumes the most fuel due to acceleration from a standstill.

What factor are involved in determining the kinetic energy of a amoving object?

The kinetic energy of a moving object is determined by its mass and velocity. The formula for kinetic energy is KE = 0.5 * mass * velocity^2, where KE is kinetic energy, mass is the object's mass, and velocity is its speed.

What is 1500 km per hour in miles per minute?

To convert 1500 km per hour to miles per minute, first convert kilometers to miles by multiplying by 0.6214. 1500 km/hr * 0.6214 = 932.1 miles per hour. Next, divide miles per hour by 60 to get miles per minute: 932.1 miles/hr / 60 min ≈ 15.5 miles per minute.

What is 500 yards per hour in meters per minute?

500 yards per hour is approximately equivalent to 228.6 meters per hour. To convert this to meters per minute, you would divide by 60 (as there are 60 minutes in an hour), resulting in approximately 3.81 meters per minute.

What is 12000 miles per year in feet per minute?

To convert miles per year to feet per minute, we first convert miles to feet by multiplying by 5280 (1 mile = 5280 feet). Then we convert years to minutes by multiplying by 525600 (1 year = 525600 minutes). Therefore, 12000 miles per year is equivalent to (12000 * 5280) / 525600 = 120.8 feet per minute.

What is 15275.9 miles per year in meters per hour?

To convert 15275.9 miles per year to meters per hour, first convert miles to meters and years to hours. There are 1609.34 meters in a mile and 8760 hours in a year. Calculate: 15275.9 miles/year * 1609.34 meters/mile / 8760 hours/year. The result is approximately 2798.7 meters per hour.

What is 88.88 feet per second in meters per hour?

There are 5280 feet in one mile. Therefore, 38 miles per hour is equal to 38 x 5280 = 200640 feet per hour.

There are 3600 seconds in one hour. therefore, 200640 feet per hour is equal to 200640/3600 = 55.73 recurring (that is, 55.73333...) feet per second.

What is 217.65 feet per second in meters per hour?

To convert feet per second to meters per hour, you first convert feet to meters by multiplying by 0.3048 and then convert seconds to hours by dividing by 3600. Therefore, 217.65 feet per second is approximately 148.53 meters per hour.

A slow moving steamroller has a large amount of kinetic energy too?

Although a slow-moving object may not have a high speed, it can still possess a significant amount of kinetic energy if it has a large mass. This is because kinetic energy depends not only on speed but also on the object's mass. In the case of a steamroller, its large mass contributes to its substantial kinetic energy even when moving slowly.

Is electric potential energy a vector or scalar quantity?

Electrical Potential Energy is a scalar or real number. Ep = zc e2 /4pi r.

Total Energy is a Quaternion, the sum of the real or potential energy and the vector energy, Ev= mcV;

E = Es + Ev = zc e2 /4pi r + mcV where Ev = mcV and V is the vector velocity.

What energy that is the total amount of kinetic and potential energy?

well the sum of potential and kinetic energy must equal zero because if a body is at rest initially it possess potential energy but when it gets into motion all those potential energy will be converted to kinetic energy, Basically kinetic energy is a result of potential energy.

Answer2:

The sum of potential energy and Kinetic energy is quaternion energy. kinetic energy is vector energy and potential energy is scalar energy. The sum of a scalar and a vector is a quaternion. William Rowan Hamilton discovered this in 1843. Currently Physics does not recognize kinetic energy as a vector.

The sum of gravitational potential and kinetic energy is E = -mMG/r + mcV where mcV is the kinetic/vector energy. This vector energy is the source of "dark energy". It is also the reason the Cosmos is in equilibrium (not contracting), in that it balances the gravitational force of attraction with mcDel.V, the centrifugal force of expansion. The centrifugal force is the divergence force from a vector, the kinetic energy mcV, a vector energy.

Is heat energy a kinetic energy or potenail energy and why?

Heat energy is a form of kinetic energy because heat is related to the motion of particles. This means heat is a form of kinetic energy. Adding heat energy to an object makes it hotter and causes its particles to move faster. That is why heat energy is a form of kinetic energy.

Answer

Heat is the name we give to energy in transit from a warmer body to a cooler body. So it's NOT a form of 'kinetic energy'; what the original answer defines is 'internal energy', not heat!

Do you add or subtract to calcuate mechanical energy?

To calculate mechanical energy, you typically add the kinetic energy (0.5 * mass * velocity^2) to the potential energy (mass * gravity * height). The total mechanical energy is the sum of these two forms of energy.

What was carl Lewis top speed?

The fastest running speed ever recorded is held by Ben Johnson (Canada) and Carl Lewis (USA) who both reached a peak speed of 0.83 seconds over 10 m (43.37 km/h or 26.9 mph) during the 1988 Olympic Games 100-m final in Seoul. And since Ben's performance was aided by steroids, it's invalid. This gives Lewis the fastest recorded human speed record holder.

When calculating acceleration to find the change in velocity you subtract the what velocity from the final velocity?

When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.

What kind of energy does the chain have that's pulling the car up to point A is it potential or kinetic?

The chain pulling the car up to point A is exerting kinetic energy because it is in motion and doing work on the car. When the car reaches point A, the energy can be converted into potential energy due to its increased height above the ground.
