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?
- Identify the object of interest. 2. Represent the object as a dot. 3. Draw vectors representing forces acting on the object, originating from the dot. 4. Label each force vector.
How do you simplify problem-solving using a free-body diagram?
- Draw the free-body diagram. 2. Choose a coordinate system. 3. Resolve forces into components along the axes. 4. Apply Newton's laws.
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.
