... force on an object can be calculated by multiplying its mass by (the acceleration due to gravity), that is :W = mg, where g =9.8 Newton/kg or m/s2. It also acceptable to approximate this to 10 N/kg. This force acts vertically downwards and can be considered to act through the centre of the object, t ...

... The lob in tennis is an effective tactic when your opponent is near the net. It consists of lofting the ball over her head, forcing her to move quickly away from the net (see the drawing). Suppose that you loft the ball with an initial speed of 15.0 m/s, at an angle of 50.0° above the horizontal. At ...
