Question

Describe how throwing a ball does work

Answer 1

║⊕ANSWER⊕║

• The second law of motion states that force on an object is equal to the mass of the object multiplied by its acceleration.
• If we apply this law to a football, it tells us that the amount that the ball accelerates depends on the force applied by the quarterback and the mass of the ball.
• The forces on a thrown ball after it leaves the thrower's hand are the force of gravity and possibly the force of air resistance.
• The force of gravity at the surface of the Earth is the gravitational acceleration at that location (9.8 meters per second per second) times the mass of the ball.
• Actually, when you throw the ball up into the air the ball will not only be acted on by gravity but friction and resistance from the air molecules colliding with the movement of the ball.
