Problem Overview:
The task is to classify the given images into two categories:
Contact Force and
Non-Contact Force.
-
Contact Force: A force that acts when two objects are in direct physical contact with each other.
-
Non-Contact Force: A force that acts between two objects without any physical contact.
Images Description:
1.
Image 1: A person lifting weights.
2.
Image 2: A person skydiving.
3.
Image 3: A balloon floating in the air.
4.
Image 4: A child drawing water from a well using a bucket.
5.
Image 5: A magnet attracting a piece of metal.
6.
Image 6: A child standing on a skateboard.
Solution:
#### Step 1: Analyze Each Image
1.
Image 1 (Person lifting weights):
- The person is directly interacting with the weights by lifting them using their hands.
- This involves physical contact between the person and the weights.
-
Classification:
Contact Force
2.
Image 2 (Person skydiving):
- The person is falling through the air due to gravity.
- Gravity is a non-contact force because it acts at a distance without requiring physical contact.
-
Classification:
Non-Contact Force
3.
Image 3 (Balloon floating):
- The balloon is floating due to buoyant force, which is caused by the difference in air pressure around the balloon.
- Buoyant force is a type of non-contact force.
-
Classification:
Non-Contact Force
4.
Image 4 (Child drawing water from a well):
- The child is pulling the bucket up using a rope.
- The force is applied through the rope, which is in direct contact with the bucket.
-
Classification:
Contact Force
5.
Image 5 (Magnet attracting metal):
- The magnet is attracting the metal without any physical contact.
- Magnetic force is a non-contact force.
-
Classification:
Non-Contact Force
6.
Image 6 (Child on a skateboard):
- The child is pushing off the ground with their foot to move the skateboard.
- This involves physical contact between the foot and the ground.
-
Classification:
Contact Force
#### Step 2: Categorize the Images
-
Contact Force:
- Image 1 (Person lifting weights)
- Image 4 (Child drawing water from a well)
- Image 6 (Child on a skateboard)
-
Non-Contact Force:
- Image 2 (Person skydiving)
- Image 3 (Balloon floating)
- Image 5 (Magnet attracting metal)
Final Answer:
\[
\boxed{
\begin{array}{ll}
\text{CONTACT FORCE} & \text{NON-CONTACT FORCE} \\
\text{Image 1} & \text{Image 2} \\
\text{Image 4} & \text{Image 3} \\
\text{Image 6} & \text{Image 5} \\
\end{array}
}
\]
