A hockey puck wont slide very far on concrete or asphalt, but it will slide for a very long time on ice. Why is this?

Answer:

Concrete and Asphalt are much rougher surfaces and have a higher coefficient of friction because they generate more resistance to an object in motion. Ice has less friction and less energy is lost to heat, causing the puck to slide much further.

When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.

Which law describes how the Earth applies a gravitational force on the Moon, the Moon applies a gravitational force on Earth? *
nikdorinn [45]
The answer is Newton's 3rd Law. The reason why is because a force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject ofNewton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.

Newton's Laws of motion describe the motion of an object based on the applied force

The correct option that gives the relationships between the forces is the the option;

\underline{F_{ball}}<u> on bat</u> = \underline{F_{bat}}<u> on ball</u>

<em>(Either option A or B without the minus symbol before </em>F_{bat}<em>, likely typographical error)</em>

<em />

Reason:

Force exerted on the bat by the ball = F_{ball}

Force exerted on the ball by the bat = F_{bat}

Given that the batter hits the ball with the bat, the force exerted by the bat on the ball, F_{bat}, is reacted to by the force of the ball acting on the bat, F_{ball}

According to Newton's third law of motion, action and reaction are equal and opposite. Therefore, at the moment when the ball hits the bat, we have;

\underline{F_{ball}}<u> on bat</u> = \underline{F_{bat}}<u> on ball</u>

<em>Where the force of the bat is high, the ball is accelerated to travel at high speed</em>
