Question

non - contact forces: gravity and the difference between mass and weight
section a: match the words in column a with their explanations in column b section a:

1. gravity
2. non - contact force
3. mass
4. weight
5. newton (n)

a. the force exerted by gravity on an object.
a. a unit of force in the international system of units (si).
a. a force that acts at a distance without physical contact.
a. a measure of the amount of matter in an object.
a. the force that pulls objects toward the centre of the earth.

Explanation:

• Gravity is the force that pulls objects toward the Earth's center.
• Non - Contact Force acts at a distance without physical contact.
• Mass measures the amount of matter in an object.
• Weight is the force exerted by gravity on an object.
• Newton (N) is a force unit in SI.

Answer:

1. Gravity - The force that pulls objects toward the centre of the Earth.
2. Non - Contact Force - A force that acts at a distance without physical contact.
3. Mass - A measure of the amount of matter in an object.
4. Weight - The force exerted by gravity on an object.
5. Newton (N) - A unit of force in the International System of Units (SI).
