Motion is a topic in physics that is sometimes hard to understand. When we talk about motion we think about acceleration, velocity, time and displacement. In the case of projectile motion, we usually disc...

1st Law - a body will move with constant velocity or remain at rest unless acted on by a resultant force
2nd Law - F = ma. The rate of change of momentum of an object is equal to the resultant force ...

first, convert to metres:10cm = 0.1mlens power = 1/focal lengthpower = 1/0.1 =10units are Dioptres, Dso the power of the lens is 10 D

The concept of time is influenced by the force of gravity. On a planet, gravity acts on every object within its gravitational field. The closer the object is to the surface of the planet, the greater infl...

Temperature is defined as the average kinetic energy of a substance, and it is what determines whether an object is a solid or a liquid. When the temperature is low, the average kinetic energy of the subs...
