The answer depends on how the body is moving:

  • in 2-dimensional space or 3-d,
  • in a straight line or not
  • at a constant velocity of not
  • at a constant acceleration or not.

For example, the equation for a body moving in simple harmonic motion is

d2y/dx2 = -w2*x

Why you use partial differential equation?

PDEs are used in simulation of real life models like heat flow equation is used for the analysis of temperature distribution in a body, the wave equation for the motion of a waveforms, the flow equation for the fluid flow and Laplace’s equation for an electrostatic potential.


Application of differential equation in temperature?

Newton's equation of cooling is a differential equation. If K is the temperature of a body at time t, then dK/dt = -r*(K - Kamb) where Kamb is the temperature of the surrounding, and r is a positive constant.


How do you describe inertia?

the tendency of a body at rest to remain at rest and of a body in motion to remain in motion


What is the term used to describe a body's resistance to a change in motion?

In physics it is inertia


The term used to describe the motion of a planet?

A better approach is to try to make more general the characteristic of a body to resist change in motion. The characteristic is called inertia. kinematics


Which of following is the term used to describe a body's resistance to a change in motion?

Inertia, inertial mass, or mass. All the same.


Three ways to describe motion?

1. Translatory motion:Translatory motion is that in which all the particles of a body move through the same distance in the same time.When a body moves along a straight line, it is called Rectilinear motion.When a body moves along a curved line, it is called Curvinlinear motion.2. Rotatory motion:Rotatory motion is that in which a body moves about a fixed axis without changing its position.3. Oscillatory motion:Oscillatory motion is that in which a body moves to and fro about its mean position.4. Periodic motion:Periodic motion is that which repeats itself after regular intervals of time.5. Repetitive motion:Repetiive motion is that which occurs again and again.


A net force changes the state of?

A net force on a body can stop the motion of a body , can create the motion of a body and can change the direction of motion of a body .


Is abody at rest in uniform motion?

no when the body the body is in motion only


What is motion and no motion?

When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.


What is the difference between linear motion and random motion?

Linear Motion is motion of object/body along a straight line.Random Motion is the motion of an object/body along a disordered or irregular line.


Meaning of the curvilinear motion?

when a body moves along a curved line , the motion described by the body is called curvilinear motion
