Newton's Laws of Motion correct answers (1) An example of Newton's First Law is a coasting bicycle on a long, level, straight stretch of highway. If the bicyclist is moving with constant velocity and happens to ride through a large mud puddle on the road, the bicycle will slow down or even stop. The external frictional force provided by the mud puddle had the effect of changing the velocity of the bicycle and rider. (2) Newton's Second Law is usually stated as a deceptively simple equati...

DIstance - · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement - · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position - · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direction matters. But distance is a scalar....

According to newtons second law of motion if the net force of an object increases while the mass of the object remains constant, what happens to acceleration ?` - - Acceleration increases if the earth moved to half its current distance from the sun, how would the force of gravity by the by the sun on the earth change? - - it would become 4 times stronger What did newtons law of universal gravitation tell us about how gravity works ? - - the force of gravity on the sun will be stronger on an...
