... 2. As a rocket takes off to the sky, it’s speed increases. Explain why. F = m × a; Newton second law states that acceleration of an object is directly proportional and in the same direction as the applied force, and inversely proportional to its mass. Therefore, as the rocket takes off to the sky, i ...

... Consider the model at right of a person bending forward to lift a 200-N object. The spine and upper body are represented as a uniform horizontal rod of weight 350 N, pivoted at the base of the spine. The erector spinalis muscle, attached at a point 2/3 of the way up the spine, maintains the positio ...
