Newton’s second law of motion stated that the acceleration of an object produced by a net force is directly proportional to the magnitude of the net force in the same direction of the net force and inversely proportional to the mass of the object. The equation is,   $a=\frac{F_{net}}{m} $  ... Read More

When evaluating the sugar levels between a strawberry and a lemon, one would automatically assume that a strawberry contains more sugar due to its sweet taste compared to that of a lemon.
