What has more kinetic energy a mass of 200 grams or a mass of 2000 grams or a mass of 20000 grams?
Assuming all have equal velocity the greater mass (20000g) will have the greater kinetic energy.
What type of energy is contained in a moving bullet?
velocity Kinetic energy is equal to (1/2)mv2, where m is mass and v is velocity. Higher velocities contribute even more to higher kinetic energies than higher masses since velocity is squared in the equation. For comparison, a 6.35 kg bowling ball moving at 7.6 m/s will have a kinetic energy of 183.4 Joules. A 0.02 kg bullet moving at 200 m/s will have a kinetic energy of 400 Joules. (Increase that to 300 m/s, and the kinetic energy moves up to 900 Joules.)
How converts gravitational potential energy into mechanical energy?
question : a 10 kg body is allowed to freefall from rest from a height of 10 m, what will be its velocity ? assume g = 10 (m/s)/s the potential energy lost will = kinetic energy gained mgh = 10*10*10 = 1000 joules velocity after fall = sq root (2*g*s) = 14.14 m/s ke = 0.5*m*v^2 = 0.5*10*200 = 1000 joules
If the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point what is the kinetic energy of the swing at its lowest point if mechanical energy is conserved?
150J, as the potential energy has been converted to kinetic energy as the swing accelerates downwards (and forwards) from the top of its swing. Therefore the decrease in potential energy corresponds directly to the increase in kinetic energy if we are ignoring things like friction. So KE = 200-50= 150
What is the kinetic energy of a 30 gram bullet that is traveling at 200 m s?
Kinetic energy = 0.5.m.v2 unit m = mass [=] kg v = velocity [=] m/s Gryazev-Shipunov GSh-30-2 firing 30 × 165mm bullet, bullet mass is 0.4 kg with velocity of 880 m/s Help your self press the calculator for the kinetic energy. Unit calculate is in Joules
Is it true that the temperature of a sample of steam increases from 100 to 200. The average kinetic energy of its particles doubles?
False
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
200 joules at 20m/s
If error in the measurement of momentum of a particle is 100 percent then the error in the measurement of kinetic energy is what?
p=mv %errror in p= %error in m+%error in v lowest value of m=0 hence %error in velocity=100% k.e=%error in mass=2*%error in velocity K.E=200% similarly K.Eminimun=100% total error in K.E = 100+200 =300 hence error in ke = 300%
Is an athlete running a kinetic energy?
To walk you need to expend mechanical energy in forcing your body forwards through forcing your leg muscles to react with the ground through your feet. Your muscles obtain the energy from chemical reactions within your body, and ultimately from the food you have digested.
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
What is the kinetic energy of 4 kilograms of bowling ball travelling down the lane at 10 meter per second?
200
Is temperature a measure of the average potential energy of each particle within an object?
It would not be the potential energy because potential is the measure of energy that is not in motion yet. When you measure the temperature and it reads 200 degrees YOU WILL FEEL IT because the objects molecules are in motion. If you measured its potential energy at this point of 200 degrees it would probably be close to zero if not zero. When you measure the temperature you are measuring the kinetic energy. The kinetic energy is the measure of how much energy the molecules have that are in motion.
