In all collisions, provided there are no external forces, momentum is conserved. This is the law of conservation of momentum. However, kinetic energy is not conserved in all collisions. An inelastic colli...
This question is not particularly tricky as long as it is read carefully. First, calculate the masses of the Star and the Exoplanet. Double the mass to find the star mass (M). To find the planet mas...
Once you note that the height is constant, the key thing to remember here is that there is no unbalanced force acting on the mass. By this, I mean that since the mass is not accelerating (it is actually a...
a) Determine the upward force produced by the droneWe can simplify the problem by drawing a free body diagram. This allows us to analyse the forces involved. We are told the drone is stationary, meaning t...
A boson is a "force-carrier": a particle that corresponds to one of the fundamental forces of nature. There are four fundamental forces, which include: Gravity, Electromagnetism, Weak Nuclear Fo...
