... A 2.73-kg lamp is sitting on a table as shown. The lamp has a base with a diameter of 18.0 cm, a height of 68.7 cm. The coefficient of static friction between the base of the lamp and the table is 0.32. A horizontal force, F, is applied to the central column of the lamp at a height of h. What is the ...

... Any discussion of biomechanics must begin with a tribute to Sir Isaac Newton and his three “Laws of motion”! Newton’s theories (and biomechanics) rests on two assumptions: physical equilibrium and the conservation of energy. Equilibrium: when more than one force acts on a body but the sum of the for ...

... What happens if you are standing on a skateboard or a slippery floor and push against a wall? You slide in the opposite direction (away from the wall), because you pushed on the wall but the wall pushed back on you with equal and opposite force. Why does it hurt so much when you stub your toe? When ...
