Basic Physics Dynamics Problem

In summary, static equilibrium refers to an object at rest with no net force, while dynamic equilibrium is an object in motion with no net force. Newton's first law of motion relates to basic physics dynamics problems by stating that an object will remain at rest or in motion unless acted upon by an external force. Linear momentum is the product of an object's mass and velocity, while angular momentum is the product of an object's moment of inertia and angular velocity. Conservation of energy applies to basic physics dynamics problems by stating that energy cannot be created or destroyed, only transferred or transformed. Forces play a crucial role in basic physics dynamics problems by causing changes in an object's motion and must be understood and analyzed to solve these problems.

Homework Statement


If mu = 0.2 find the maximum angle before slipping occurs
Diagram: A ramp in the shape of a right triangle that is 30 degrees above the horizontal. A mass is on the ramp and tied to it is a string that runs around the ramp to the vertical side of the ramp where another mass is held in the air.

Homework Equations


F(net)=ma
F(friction)=(mu)*(Normal Force)

The Attempt at a Solution


F(friction) = 0.2*(Normal Force)
F(net) = 0
F(friction)-(Fgravitytan(theta))=0
0.2F(gravity) - (Fgravitytan(theta)) = 0

1. What is the difference between static and dynamic equilibrium?

Static equilibrium refers to a state in which an object is at rest and has no net force acting on it. In contrast, dynamic equilibrium is a state in which an object is moving at a constant velocity with no net force acting on it.

2. How does Newton's first law of motion relate to basic physics dynamics problems?

Newton's first law of motion states that an object will remain at rest or in motion at a constant velocity unless acted upon by an external force. This law is often used to analyze and solve basic physics dynamics problems.

3. What is the difference between linear and angular momentum?

Linear momentum is the product of an object's mass and its velocity, while angular momentum is the product of an object's moment of inertia and its angular velocity. Linear momentum is a measure of an object's linear motion, while angular momentum is a measure of an object's rotational motion.

4. How does conservation of energy apply to basic physics dynamics problems?

Conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This principle is often used to analyze and solve basic physics dynamics problems involving the exchange of energy between different forms.

5. What role do forces play in basic physics dynamics problems?

Forces are the driving factor in basic physics dynamics problems. They can cause changes in an object's motion, such as acceleration, deceleration, or changes in direction. Understanding and analyzing the forces acting on an object is crucial in solving these types of problems.
