An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
An object that has linear kinetic energy must be in motion and have mass. The linear kinetic energy of an object is related to its velocity and mass, as given by 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 velocity of the object.
If the particles in an object have more kinetic energy, then the object's temperature must be higher. This is because an increase in kinetic energy of the particles results in higher average speed and therefore a higher temperature of the object.
The object with particles having more kinetic energy will have a higher temperature than the object with particles having less kinetic energy.
An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must have momentum, velocity, and speed because if an object is in motion (has kinetic energy) it must be either gaining, losing, or at a constant momentum, it must have a velocity (basically speed) and speed because when an object is in motion, it MUST have a certain velocity or speed.
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.

If an object has no kinetic energy, it means that it is not in motion. Kinetic energy is the energy an object possesses due to its motion, so if there is no motion, there is no kinetic energy present.
Not necessarily. An object can have kinetic energy without having potential energy. For example, a moving car has kinetic energy but may not have any stored potential energy depending on its position.
An object has no kinetic energy when it is at rest or not in motion. Kinetic energy is the energy an object possesses due to its motion, so when there is no motion, there is no kinetic energy present.
an object has no kinetic energy if it is not moving
When an object is in motion, its kinetic energy increases. Kinetic energy is the energy of motion, and it depends on the object's mass and speed. The faster an object moves or the heavier it is, the more kinetic energy it has.
Yes, an object can have both mechanical energy and kinetic energy. Mechanical energy is the sum of an object's potential energy and kinetic energy. Kinetic energy is the energy an object possesses due to its motion, whereas potential energy is the energy stored in an object due to its position or state.
