What is Newton’s Third Law of Motion 2 points?

Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Why … Read more

What is constructive and destructive interference of waves?

Constructive interference occurs where the lines (representing peaks), cross over each other. In other words, when two waves are in phase, they interfere constructively. Destructive interference occurs where two waves are completely out of phase (a peak lies at the midpoint of two waves. What are the conditions of constructive and destructive interference? The condition … Read more

Is angular momentum the same as rotational momentum?

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity – the angular momentum of a system remains constant unless acted on by an external torque. How do you calculate rotational angular momentum? p … Read more

How do you know which equations to use in physics?

How do you know which motion equation to use? What equations should I memorize for AP Physics 1? Is AP Physics 1 hardest? AP Physics 1 consistently tops the list of most difficult AP classes. AP Physics 1 explores college-level content and covers foundational science knowledge. Students with strong math and science skills are most … Read more

What is a qualitative argument?

Given a qualitative network modeling a complex sys- tem, we are interested in defining the notion of ar- guments for and against claims regarding changes in values of variables relative to a given input perturba- tion . An qualitative argument is a directed path in a qualitative network. What is qualitative quantitative translation? This skill … Read more

How do you calculate angular velocity and acceleration?

What is the angular velocity of a Ferris wheel? A Ferris wheel rotates at an angular velocity of 0.24 rad/s. Starting from rest, it reaches its operating speed with an average angular acceleration of 0.030 rad/s2. What is the SI unit for angular velocity? The SI unit of angular velocity is expressed as radians per … Read more

How do you find buoyant force with tension?

Is regular physics easier than AP Physics? Overall though, AP probably won’t be much harder than the regular class, but then again it varies from school to school and person to person. Is AP Physics 1 the same as college physics? The AP Physics 1 course is the equivalent of a first-semester, algebra-based college physics … Read more

What is equilibrium formula?

The equilibrium equations (balance of linear momentum) are given in index form as(1.4)σji,j+bi=ρu¨i,i,j=1,2,3where σij are components of (Cauchy) stress, ρ is mass density, and bi are body force components. What are the 3 equations of equilibrium? In order for a system to be in equilibrium, it must satisfy all three equations of equilibrium, Sum Fx … Read more

What law of motion is riding a roller coaster?

Most roller coasters run by the Law of Inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started. What forces are affecting you as you move through a roller coaster ride? At every point on a roller coaster ride, gravity is pulling you straight … Read more
