Question

Match each Descriptor on the left with the best Force on the right. You may use some forces more than once.

Descriptor

A. An apple falls from a tree branch

B. A person uses a rope to pull a friend on a sled

C. A magnet holds a picture on a fridge

D. A person pulls a bow back and shoots the arrow

E. A sock is stuck to a sweater as it comes out of the dryer

F. When a person stops pedalling, the bicycle slows down

G. A meteor travelling through space moves faster and faster as it approaches Earth

H. A bungee cord pulls a jumper back up toward the platform from which he jumped

I. Your hands become warmer as you vigorously rub them together

J. When combing your hair, you notice hairs move outward from your head toward the comb Force
Option:
A. Gravitational

B. Tension

C. Magnetic

D. Elastic

E. Friction

F. Electrostatic

Answer 1

Each descriptor describes a different physical situation, and each is best matched by a corresponding force: gravitational, tension, magnetic, elastic, electrostatic, or frictional forces.

Step-by-step explanation:

To match each descriptor with the appropriate force, we need to examine the context of each situation described on the left and relate it to the types of forces available on the right.

1. Gravitational force is responsible for the apple falling from the tree, as the apple is pulled towards the Earth's center.
2. Tension force is seen when a person uses a rope to pull a friend on a sled, the rope provides the tension force.
3. Magnetic force is evidenced by a magnet holding a picture on a fridge.
4. Elastic force comes into play when a person pulls a bow back and releases the arrow.
5. Electrostatic force explains why a sock sticks to a sweater, due to static electric charges.
6. Friction is a force that acts to slow down the bicycle when the person stops pedalling.
7. Gravitational force again comes into play as it causes a meteor to accelerate as it approaches Earth, due to the gravitational attraction between the Earth and the meteor.
8. Elastic force is seen when a bungee cord pulls a jumper back up towards the platform; the bungee cord behaves like an elastic material.
9. Friction causes your hands to become warmer as you rub them together.
10. Electrostatic force can explain the hairs moving toward the comb after combing, due to static electricity generated by combing.
