How do you find the speed given joules and mass?
Use the formula for Kinetic Energy (KE), which is the energy due to the motion of an object. KE = (1/2) * (mass) * (velocity)2 where KE is in joules, mass is in kg, and velocity (or speed) would be in meters/sec...Just substitute the appropriate numbers, rearrange and solve for velocity
How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
How do you find distance given acceleration and speed?
acceleration times speed
How do you find the speed of an object given distance and time?
Divide the distance by the time; the quotient is speed.
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
How do you find mean kinetic energy when given only mass and horizontal distance traveled?
To find the mean kinetic energy with only mass and horizontal distance traveled, you would also need to know the initial and final velocities of the object. Once you have these values, you can calculate the mean kinetic energy using the formula: KE = 0.5 * m * ((v_final)^2 - (v_initial)^2), where m is the mass and v is the velocity.
How do you find kinetic energy if no final velocity is given?
You can calculate kinetic energy using the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. If the final velocity is not given, you would need more information or assumptions to solve for kinetic energy.
How do you find speed in Kinetic Energy?
To find the speed in Kinetic Energy, you can use the formula: KE = 0.5 * m * v^2, where KE is the Kinetic Energy, m is the mass of the object, and v is the speed of the object. Rearrange the formula to solve for v: v = sqrt(2 * KE / m). Plug in the values of Kinetic Energy and mass to calculate the speed.
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
A change in an object's speed has a greater effect on its kinetic energy than a change in mass. Kinetic energy is proportional to the square of the velocity, so even a small change in speed can result in a significant change in kinetic energy. On the other hand, mass only affects kinetic energy linearly.
How do you find the speed with mass and kinetic energy?
|v| = sqrt( 2 * KE / m ), with |v| being speed.
How do you find particles maximum speed in a potential energy diagram?
To find a particle's maximum speed in a potential energy diagram, you need to locate the point in the diagram where the potential energy curve is at its lowest. The maximum speed of the particle at that point is determined by the total mechanical energy it possesses, which is the sum of its kinetic and potential energies. At the point where the potential energy is lowest, the kinetic energy is at its maximum, indicating the particle's maximum speed.
What makes an object have more kinetic energy?
An object has more kinetic energy when its mass is larger or when its velocity is higher. Kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2, so increasing either the mass or the velocity will result in a higher kinetic energy.
How do you find speed using work kinetic energy theorem?
To find the speed using the work-energy theorem, you need to equate the work done on an object to its change in kinetic energy. The equation is: Work = ΔKE = 1/2(mv² - mu²), where m is the object's mass, v is the final velocity, and u is the initial velocity. Solve for v to find the final speed.
How do you calculate kinetic energy with mass and velocity?
The formula to calculate kinetic energy is KE = 0.5 * mass * velocity^2. Simply multiply the mass of the object by half of its velocity squared to determine its kinetic energy.
Suppose you pedal a 25kg bicycle at 1.5 m. Find the kinetic energy of bicycle?
The kinetic energy of an object is given by the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. Plugging in the values, the kinetic energy of the bicycle can be calculated as KE = 0.5 * 25 * (1.5)^2 = 28.125 J.
How do you find the kinetic energy of a gas when given molecules and temperature?
The relation between temperature and energy is given by the Boltzmann equation. Boltzmann found a consatn( called the boltzmann constant) that relates the two. That is Energy=k*T
How do you find the speed given joules and mass?
Use the formula for Kinetic Energy (KE), which is the energy due to the motion of an object. KE = (1/2) * (mass) * (velocity)2 where KE is in joules, mass is in kg, and velocity (or speed) would be in meters/sec...Just substitute the appropriate numbers, rearrange and solve for velocity
