Answer:
The two main factors that affect kinetic energy are mass and speed.
Explanation:
Kinetic energy is the energy that is caused by the motion. The kinetic energy of an object is the energy or force that the object has due to its motion. Your moving vehicle has kinetic energy; as you increase your vehicle's speed, your vehicle's kinetic energy increases.
Have a great day! :D
Answer:
Zero
Explanation:
Given:
speed of the observer,
length of the car,
speed of light,
Now as we notice that the observer is moving at a general velocity which is very much less than the speed of the light and hence he/she cannot observe the relativistic length of the car, here only classical physics is applicable.
So the observer will observe the length of the car to be the same as its original length during the motion.
Answer: impulse and momentum
Explanation:
vibrations in strings, ripples on water surface and electromagnetic waves.
