A. "My coffee spilled all over because you slammed on your brakes!"
B."The box of cotton is much easier to lift than the box of books."
C. "That bat hurt my hands when I hit the ball!"
D. "I can't hit the ball farther than you because you're stronger than I am."
Answer:
1. law of universal gravitation -"The box of cotton is much easier to lift than the box of books."
2. 1st law of motion (law of inertia) - "My coffee spilled all over because you slammed on your brakes!"
3. 2nd law of motion - "I can't hit the ball farther than you because you're stronger than I am."
4. 3rd law of motion - "That bat hurt my hands when I hit the ball!"
Explanation:
Law of gravitation states that there exists an attractive force between two objects having mass. The magnitude of the force depends upon the masses of the two objects and inversely proportional to the distance between them. Thus, greater the mass, greater would be the force. weight of an object is determines the gravitation pull of the Earth on the mass of the object. Thus, it is easier to lift a box of cotton which is lighter in weight than a box of books.
Newton's first law states that an object remains in state of rest or motion unless exerted by an unbalanced external force. Thus, when you are sitting in the car and the driver applies break suddenly, you experience a pull force because you continue to move forward while the car suddenly decelerates and if you would be holding coffee, it can spill.
Second law of motion states that force is rate of change of momentum. Momentum depends on the mass and velocity of the object. Greater the mass, greater would be momentum. Thus, A person who is stronger would be able to hit the ball harder and hence faster than the other.
Third law of motion states that, for every action, there is equal and opposite reaction. Thus, when when you a ball with the bat, you are applying force with your hands. Hence, your hands would also experience an equal amount of force in the opposite direction and you would get hurt.
