Which force acts along a rope, string, cable, or similar flexible element connecting a rigid body to another object?
Tension Force
Under what conditions does air resistance force arise?
When the rigid body moves through a fluid
What affects the magnitude of the air resistance force?
Objects' shape and size
In a scenario where an object is moving through air, which force opposes the motion due to the interaction between the object's surface and the surrounding fluid particles?
Air Resistance Force (Drag)
What type of force can be either static, preventing motion, or kinetic, opposing motion?
Frictional Force
Which force typically has a magnitude equal to the force pressing two objects together but can vary depending on the specific situation?
Normal Force
What material property affects the magnitude of the frictional force between two objects in contact?
Coefficient of Friction
Which force arises when a rigid body is connected to another object by a rope, string, or cable?
