Question

if a penny and a brick were dropped at the same time in the air, what would happen? a. the penny would fall faster than the brick. b. the brick would fall faster than the penny. c. the brick and penny would fall at the same speed. which of newton’s three laws of motion says that forces always act in pairs? a. newton’s first law of motion b. newton’s second law of motion c. newton’s third law of motion which of newton’s three laws of motion has to do with inertia? a. newton’s first law of motion b. newton’s second law of motion c. newton’s third law of motion isaac newton was the first person to discover the force of ___. a. friction b. gravity c. magnetism which two reasons are why newton’s laws are called laws and not theories? □ study of his laws is required by the governments of several nations. □ the laws have always been observed to be true. □ the laws have been proven by many other scientists. □ study of his laws helps scientists regulate which concepts are tested. how did newton make sure his ideas about gravity were true? a. he asked other scientists to look over his data. b. he made observations of animals in his mother’s garden. c. he repeated experiments to test his ideas about gravity and force.

Explanation:

1. In air, air resistance affects lighter objects more, so the brick falls faster.
2. Newton's third law states forces act in equal, opposite pairs.
3. Newton's first law defines inertia (objects resist motion changes).
4. Newton is credited with discovering gravitational force.
5. Scientific laws are consistently observed true and verified by multiple scientists; government requirements and test regulation are not relevant to the definition of a law.
6. Newton validated his gravity ideas through repeated experimental testing.

Answer:

2.012) B. The brick would fall faster than the penny.
2.013) C. Newton's third law of motion
2.014) A. Newton's first law of motion
2.015) B. gravity
2.016)

• The laws have always been observed to be true.
• The laws have been proven by many other scientists.

2.017) C. He repeated experiments to test his ideas about gravity and force.
