When does an object have no kenetic energy?
Kinetic energy = (1/2) x mass x speed squared. An object will have no kinetic energy if it doesn't move.
How does mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
Which does not affect the gravitational potential energy of an object?
speed
Does speed affect gravitational potential energy of an object?
Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.
A girl who weighs 30 kg is inline skating at a speed of 5 ms. what is the girl's kenetic energy?
yellow
What does the amount of kenetic energy that a moving object has depend on?
The amount of kinetic energy an object has depends on its mass and speed.
When does an object have no kenetic energy?
Kinetic energy = (1/2) x mass x speed squared. An object will have no kinetic energy if it doesn't move.
Does the mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does kinetic energy affect speed?
The kinetic energy of an object is proportional to the square of its speed.
Which does not affect the gravitational potential energy of an object?
speed
How does kenetic enery depend on speed?
kinetic energy is proportional to square of speed. ke=.5m*v*v
How does the affect the speed of an object?
More intertia makes it so more energy is needed in order to change the speed.
Does speed affect gravitational potential energy of an object?
Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.
How does increasing the height of a ramp effect a rolling objects speed?
Because then more kenetic energy is transfered
How does increasing speed affect potential energy?
Increasing the speed will increase the KINETIC energy, not the potential energy. Of course, the potential energy may eventually be converted into kinetic energy, for example if the object moves upwards.
How do the mass and speed of an object affect the energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
