Answer 1

Answer:

yea it simply says that

Explanation:

the force of gravity will only act on a thing with matter or mass . eg : car or truck .

the force of gravity doesnt act on a mass less object . eg : light or sound .

Answer 2

Weight is the force of gravity that is exerted on the body by its mass.

• The force of gravity is referred or denoted by the letter W, or weight. F is a constant force that affects all objects close to Earth.
• All items are pulled downward toward the Earth's centre by the gravity of the planet. By dividing the object's mass, m, by the gravitational acceleration, $g = 9.8 m/s$, one can calculate the strength of the force of gravity.
• No matter which way an object is going or what other forces are acting on it, the Earth's force of gravity, $F = mg$, is always there.
• Whether an object is falling down, soaring up at an angle, resting on a table, or moving quickly upward in an elevator, all objects close to the Earth will experience a gravitational force of magnitude mg acting downward on them.
• Although there may be other forces at play as an item accelerates, gravity is always a factor.

Hence, weight is the force of gravity that is exerted on the body by its mass.
