The force that is required to keep an object moving in a circular path is the centripetal force acting on the object. Simply put, a force is what is required to cause a mass to accelerate. This is actually how Newton first thought of his law.

Keeping the force constant demonstrates an inverse proportion between acceleration and mass. This equation relates the lengths of the vector and its components. Power is a physical quantity equal to the rate at which work is done. The difference in the two time measurements represents a duration of time.

Energy is really defined as the ability to do mechanical work. For either a closed-ended resonator like blowing across the top of a pop bottlethis equation allows you to calculate the frequency of a standing wave with the integer, n, number of antinodes or loops. This equation is both the definition of average acceleration and the fact that it is the slope of a velocity-time graph.

You must know the length of the tube or string, the number of antinodes, and the velocity of the wave in the tube or along the string. Hence, if a force applied is perpendicular to the distance traveled, no work is done. The more time it takes to do the same work, the smaller the power generated, and vice-versa.

Though a bit more complex looking, this equation is really an excellent way to find final velocity knowing only initial velocity, average acceleration, and displacement. If the object moves with a constant velocity, it will have the same average velocity during all time durations. The work done on an object is found by multiplying force and distance, but there is a catch.

Therefore, in order to make a wave travel faster in a string like a guitar stringI can do any one of three things while keeping the others constant: Feel free to print out a copy and update as we go in class.

Similarly as above, if I have a series of forces acting on a mass, the sum of their y-components must be equal to the y-component of the net force on the mass. Important to note that closed-resonators are able to achieve the same resonant frequency, but at one-half the length.

This equation shows the relationship between the period of a pendulum and its length. This is a simple re-write of the old distance-equals-rate-times-time formula with average velocity defined as above. In two dimensions, the law still holds -- we just pay attention to the components of the total momentum.

With it, you could predict the fundamental frequency that would be played by a string of any length how frets are placed on a guitar.

Take note that an object can have different velocities measured from different reference frames. If the mass is not accelerated meaning: Typically, this is measured in meters, but always in units of distance. If an object goes from an initial velocity to a final velocity, undergoing constant acceleration, you can simply "average" the two velocities this way.

The variable F is the tension force in the string; the variable m is the mass of the string; and the variable L is the length of the string. Divide the net force by the mass, and you will find the acceleration of the object. This is a simplified mathematical re-statement of the law of energy conservation.

Adjust them to see how the calculations work in several situations.Given the units of force, write a simple equation relating a constant force F exerted on an object, an interval of time t during which the force is applied, and the resulting momentum of the object.

Given the units of force, write a simple equation relating a constant force F exerted on an object, an interval of time t during which the force is applied, and the %(3). Sep 19, · Given the units of force, (kg*m/s^2) write a simple equation relating a constant for F exerted on an object, an interval time t during which the force is Status: Resolved.

(b) Given the units of force, write a simple equation relating a constant force F. exerted on an object, an interval of time t during which the force is applied, and. the resulting momentum of the object, p. Look for F ∼ tαpβ with yet unknown α, β. This is a simple re-write of the definition of acceleration.

at a given radial distance. This equation shows the relationship between the period of a pendulum and its length. Hence, if a force applied is perpendicular to the distance traveled, no work is done.

The equation becomes force times distance times the cosine of the angle. Given the units of force, write a simple equation relating a constant force F exerted on an object, an interval of time t during which the force is applied, and the .
