Directions: Read and analyze the following situation. Identify what type of force are being applied. Write CF if contact force is observed and NCF if non-contact force.

1. Hitting a ball with a bat.

2. Two magnets repelling each other.

3. Pedaling a bicycle.

4. Gravity pulls you toward the ground.

5. Pulling a door open.

Answer:

Here is the analysis of the forces involved in each situation:

1. Hitting a ball with a bat: CF (Contact Force) – The bat exerts a force on the ball through physical contact.

2. Two magnets repelling each other: NCF (Non-Contact Force) – The repulsive force between the magnets occurs without physical contact, due to the magnetic field.

3. Pedaling a bicycle: CF (Contact Force) – The force applied by the rider’s legs on the pedals is transmitted through contact.

4. Gravity pulls you toward the ground: NCF (Non-Contact Force) – Gravity acts at a distance without physical contact.

5. Pulling a door open: CF (Contact Force) – The force applied to the door handle involves physical contact.
