When the speed of a moving object is doubled, its:
The kinetic energy (KE) of a moving object is given by the formula:
= 1/22
Where:
m is the mass of the object
v is the velocity (or speed) of the object
The kinetic energy is proportional to the square of the velocity. Therefore, if the velocity is doubled, the kinetic energy increases by a factor of 4.
A ball of mass 50 grams is moving with a velocity of 15 m/s. What is its kinetic energy?
The kinetic energy of an object is derived using which of the following equations of motion?
The dimension of resistance is _____.
_____ arise from the errors due to imperfect design or calibration of the measuring instrument, zero error in the instrument, etc.
The smallest value that can be measured by the measuring instrument is called
‘P’ of a body is defined as product of mass and velocity. What is P here?
Kepler’s law of areas, relates to
In Newton’s third law of motion the force acting on two bodies is _____.
Which law states that ‘Every body in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.’?
A ball of mass 50 grams is moving with a velocity of 15 m/s. What is its kinetic energy?
