... second, or a small two-seater sports car traveling the same speed? You probably guessed that it takes more force to stop a large truck than a small car. In physics terms, we say that the truck has greater momentum. We can find momentum using this equation: momentum = mass of object × velocity of obj ...

... no centripetal force – it simply refers to the net force causing the centripetal acceleration. The actual force causing the centripetal acceleration is determined from the free-body diagram (tension, gravity, friction, normal force, etc). Since F=ma and ac=v2/r, the magnitude of the centripetal f ...

... Resonance is the condition in which a time-dependent force can transmit large amounts of energy to an oscillation object, leading to a large amplitude motion. In the absence of damping, resonance occurs when the frequency of the force matches a natural frequency at which the object will oscillate. T ...

If you ask a random collection of first year students, “What do you know about relativity?” the answers might be: “All is relative?” “It all depends on your frame of reference.” “You will never measure an absolute velocity unless you look into space.” “Wasn’t it invented by the same guy that gave us ...
