All Flashcards
What is a vector quantity?
A quantity with both magnitude and direction.
Define contact force.
Force that arises from physical contact between objects, resulting from interatomic electric forces.
What is a free-body diagram?
A visual representation showing all forces acting on an object or system.
Define normal force.
The force exerted by a surface perpendicular to the contact area.
What is tension force?
The force transmitted through a rope, string, or cable when it is pulled tight by forces acting from opposite ends.
What is friction force?
The force that opposes motion between surfaces in contact.
What are the steps to create a free-body diagram?
- Represent the object as a dot. 2. Draw vectors representing all forces acting on the object, starting from the dot. 3. Label each force vector with its magnitude and direction.
How do you choose an appropriate coordinate system for a free-body diagram?
- Identify the direction of acceleration. 2. Align one axis of the coordinate system with the direction of acceleration.
What is a vector quantity?
A quantity with both magnitude and direction.
Define contact force.
A force resulting from the interaction of objects touching each other.
What is a free-body diagram?
A visual representation of all forces acting on a single object or system.
Define gravitational force (weight).
The force exerted on an object due to gravity.
What is normal force?
The force exerted by a surface on an object resting on it, perpendicular to the surface.
Define tension.
The force exerted by a rope or string when it is pulled tight.
