All Flashcards
What is the effect of increasing the angle of an inclined plane on the component of weight acting down the plane?
Increasing the angle increases the component of weight acting down the plane ().
What happens when the net force on an object is zero?
The object is in equilibrium (either at rest or moving with constant velocity).
What is the effect of increasing the coefficient of friction between two surfaces?
It increases the frictional force between the surfaces, opposing motion.
What happens if you do not include all forces acting on an object in a free-body diagram?
The net force calculation will be incorrect, leading to an incorrect determination of acceleration.
What effect does increasing normal force have on friction force?
Increasing the normal force typically increases the friction force, as friction force is often proportional to the normal force.
What happens if the applied force is greater than the maximum static friction?
The object will begin to move, and the friction force will transition from static to kinetic friction.
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.
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.
