Question

Now it's your turn to try on and decide if the force examples below are contact forces or non-contact forces. Please respond in the chatbox below with an answer for each example. Magnetic: Magnet being pulled to a metal surface. Friction: skateboard slowing down on a rough surface. Gravity: Ball falling to the ground. Electrical: Charged balloon pulling up on arm hair . Tension (pull): people playing tug-of-war. Applied (push): a person pushing a toy car . Air resistance: wind pushing on the sail of a sailboat. Spring: springs being pushed together.

Answer 1

Answer:

Magnetic: Magnet being pulled to a metal surface- non- contact force

Friction: skateboard slowing down on a rough surface- contact force

Gravity: Ball falling to the ground - non-contact force

Electrical: Charged balloon pulling up on arm hair - non- contact force

Tension (pull): people playing tug-of-war - contact force

Applied (push): a person pushing a toy car - contact force

Air resistance: wind pushing on the sail of a sailboat - contact force

Spring: springs being pushed together -contact force

Explanation:

A contact force is a type of force that can only act when two bodies touch other physically. Examples of this include a push or a pull.

A non-contact force is a type of force that can only act when two bodies do not touch other physically. Examples include; electric force, magnetic force, etc.
