When an elevator is accelerating downward, the normal force is equal to mg-ma (hence you feel a little lighter when accelerating downwards)
Therefore, the upward force of the elevator floor on the person must be less than 750N
<span>equal and acting on different objects</span>
I dont know but i know i dont lnow if this is true but the gravity is slowly going away every 4 year i dont know i think.
Hello User,
Approximately 32 electrons can be fit in the fourth energy level.
Solution:
2+4+6+10+10=32
When you hold the ball, you have potential energy, when you drop the ball, you have kinetic.
