What is time dependent force?

A time – dependent force, vec F = (8.00vec i – 4.00tvec j) , where vec F is in newtons and t is in seconds, is exerted on a 2.00kg object initially at rest. ( a) At what time will the object be moving with a speed of 15.0 m/s? ( b) How far is the object from its initial position when its speed is 15.0 m/s? (

What is force dependent motion?

In certain cases the motion of one particle could be dependent on the motion of another particle. If you were to pull particle B down particle A will move upward. While on the other hand if you were to move particle A down particle B will move upward. This is dependent motion.

How do you find velocity from time dependent force?

If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v=vi​+at gives its velocity v as a function of time, where a is its constant acceleration.

Is gravitational force time Dependent?

In our universe we have a gravitational constant – i.e gravity is not dependent on time. If gravity changed with respect to time then the gravitational force exerted by the Sun on Earth would lessen (or increase) over time with all other factors remaining the same.

What is time dependent acceleration?

Time Dependent Acceleration Allowing the acceleration to have terms up to the second power of time leads to the following motion equations for one dimensional motion. Variable acceleration.

Is work time dependent?

Work is a time-based quantity; it is dependent upon how fast a force displaces an object.

What do you mean by dependent motion explain with example?

Sometimes the motion of two or more objects are related because of a constraint. To relate the motion of the objects a constraint equation needs to be determined. A common example of dependent motion is when objects are connected by an inextensible cable.

What are velocity dependent forces?

University of Victoria. Lecture 3: Velocity Dependent Forces. The viscous force that a fluid exerts on a particle depends on velocity, F = F(v). For most problems, it suffices to expand F in powers of v and keep only the 1st and 2nd orders: F(v) = −c1v − c2v|v| − c3v3 − …

What is a velocity dependent force?

University of Victoria. Lecture 3: Velocity Dependent Forces. The viscous force that a fluid exerts on a particle depends on velocity, F = F(v).

Which force depends on velocity?

Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number.

What is velocity time dilation?

In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. When unspecified, “time dilation” usually refers to the effect due to velocity.

What is a time dependent force?

A time dependent force is one that varies with time. The actual cause of the variation may not have anything to do with time, it may be related to either internal or external factors.

What is velocity dependent force?

Velocity Dependent Forces Consider a particle of mass moving in one dimension under the action of a force, , which is a function of the particle’s speed, , but not of its displacement, . Note that such a force is intrinsically non-conservative [since it clearly cannot be expressed as minus the gradient of some potential function, ].

Why is radiation called a time dependent force?

Hence, that nuance is called a time-dependent force. In radioactivity, the amount of radiation decreases over time. For other object, that is a time-dependent force. If calculating the atom itself, most would just call that a time-study as the force changes is related to changes in the object itself.
