They are a) positive charge and b) negative charge. Properties of Charge ⇒Like charges repeal each other. ⇒Unlike charges attract each other. Coulomb’s Law The … Read more

Explain the acceleration of a falling body.

Explain the acceleration of a falling body. The acceleration of a falling body is a perfect example of uniform velocity. Due to gravity, the acceleration of a freely falling body is 9.8 ms⁻². If we drop a body from the air its velocity increases by 9.8 ms⁻¹ in 1st second. Again, its velocity increases by … Read more

Space, time, and mass in physics

Space, time, and mass in physics Classical mechanics is known as Newtonian mechanics. In this mechanics concept of three fundamental quantities has been considered. These are space, time, and mass. Space: According to Newton, space is an absolute quantity that exists in itself. It is not related to any outer or external thing and is … Read more
