Let's solve the worksheet step by step.
---
Q1: Fill in the blanks with the words given in the word bank.
Word Bank:
friction – force – stops or slows – resistance – air resistance
---
1. Friction and air resistance are types of _________.
✔ Answer: *force*
Explanation: Both friction and air resistance are forces that act on objects, opposing motion.
---
2. Friction is the force that _________ objects which are sliding past each other.
✔ Answer: *stops or slows*
Explanation: Friction resists motion between surfaces in contact, so it either slows down or stops moving objects.
---
3. A rolling ball will come to a stop because of _________.
✔ Answer: *friction*
Explanation: The ball eventually stops due to friction between the ball and the ground (and possibly air resistance), but primarily surface friction.
---
4. The force that opposes the force of gravity in the air is called the air _________.
✔ Answer: *resistance*
Explanation: Air resistance (also called drag) acts upward against gravity when an object falls through the air.
---
5. _________ stops paper from falling quickly.
✔ Answer: *air resistance*
Explanation: Paper has a large surface area and low mass, so air resistance significantly slows its fall.

✔ Q1 Answers:
1. force
2. stops or slows
3. friction
4. resistance
5. air resistance

Q2: Which type of force is present in the following pictures? Write 'A' for air resistance and 'F' for friction.
Let’s analyze each image:
####
Image 1: Person pushing a table
- The person is trying to move a heavy table.
- There is resistance between the table and the floor.
- This is
friction.
✔ Answer: F
---
####
Image 2: Parachute in the sky
- The parachute is slowing the descent of a person.
- The large surface area catches air, creating
air resistance.
✔ Answer: A
---
####
Image 3: Child sliding down a slide
- The child is sliding down a surface.
- There is contact between the child and the slide →
friction.
✔ Answer: F
---
####
Image 4: Paper airplane flying
- The airplane is moving through the air.
- Air pushes against it →
air resistance.
✔ Answer: A
---
####
Image 5: Person riding a bicycle
- The bike moves on the road.
- Tires rub against the ground →
friction (also helps with movement).
- Air also pushes against the rider →
air resistance, but the dominant interaction here is
friction between tires and road.
- However, both forces are present, but the question asks for
which type is present — since the bike is moving forward,
friction is essential for motion, while air resistance opposes it.
- But the main focus in such questions is usually the
contact-based resistance, so
friction is the key force shown.
✔ Answer: F
> Note: While air resistance is also acting, the most prominent force in this context (especially at lower speeds) is
friction between tires and road.

✔ Q2 Answers:
1. F (pushing table)
2. A (parachute)
3. F (slide)
4. A (paper airplane)
5. F (bicycle)

✔ Final Answer Summary:
Q1:
1. force
2. stops or slows
3. friction
4. resistance
5. air resistance
Q2:
- Pushing table:
F
- Parachute:
A
