What is the effect of increasing the angle of an inclined plane on the component of gravitational force parallel to the plane?
The component of gravitational force parallel to the plane increases.
What is the effect of friction on the motion of an object?
Friction opposes the motion of the object, causing it to slow down or preventing it from starting to move.
What is the effect of a non-zero net force on an object?
The object accelerates in the direction of the net force, according to Newton's Second Law ($\vec{F} = m\vec{a}$).
What is the effect of an object resting on a surface?
The surface exerts a normal force on the object, perpendicular to the surface.
What happens when the tension in a rope pulling an object increases?
The object experiences a greater force in the direction of the tension, potentially increasing its acceleration.
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 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 ($mg\sin\theta$).
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.
