# What is time dependent force?

## 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 a 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).

#### What forces are used in dance?

Many forces come into play here including friction and gravity. Once the dancer loses contact with the floor, the dancer’s center of gravity will follow a parabolic trajectory, or curved path, that is determined by the conditions of motion at the beginning of the jump.

Does force depend on time?

Force Depends on Time: F=F(t) Assuming that the motion is one-dimensional, Newton’s second law is written as the second order differential equation: md2xdt2=F(t).

Which forces are velocity dependent?

(at which the gravitational and air resistance forces balance). before it achieves its terminal velocity.

## What are 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, .

### How does force depend on time?

Force Depends on Time: Assuming that the motion is one-dimensional, Newton’s second law is written as the second order differential equation: m d 2 x d t 2 = F ( t ) . Integrating once, we find the velocity of the body. Here we assume that the body begins to move at time with the initial velocity.

#### What is K in Schrodinger equation?

Law of Motion. v(t) = ˙x(t) and x(t) given knowledge of any two positions, or any two velocities, or any combination of two, at any time. F(x) = dV dx= −kx , (5.7) where k is the“spring constant”.
