According to Newton's Second Law, what is the effect of applying a net force on an object?
The object accelerates in the direction of the net force. The acceleration is directly proportional to the net force and inversely proportional to the mass ().
What is the effect of the Earth pulling on you?
You pull on the Earth (equal and opposite force).
Identify the forces acting on the box in the Free Body Diagram.
1: Weight (Force of Gravity), 2: Normal Force, 3: Applied Force, 4: Force of Friction
What is the effect of increasing the net force on an object?
The object's acceleration increases proportionally (Newton's Second Law).
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 angle of an inclined plane on the component of weight acting parallel to the plane?
The component of weight acting parallel to the plane increases, potentially increasing the object's acceleration down the plane.
What happens when an object exerts a force on another object?
The second object exerts an equal and opposite force back on the first object (Newton's Third Law).
What is the effect of increasing the coefficient of friction between two surfaces?
The frictional force between the surfaces increases, opposing motion more strongly.
