## Which equation describes the position of the object as a function of time?

equation of motion x

The equation of motion x(t) describes the position of the car as a function of time. The velocity describes the change in the position of the car, or mathematically v(t)≡rate of change in x(t).

**How does position depend on time?**

The position of the object will in general be a function of time: x(t). shows the position as a function of time for an object at rest, and for objects moving to the left and to the right. The slope of the curve in the position versus time graph depends on the velocity of the object. See for example Figure 2.3.

### What is the equation that relates an object’s position as a function of time when it travels with constant acceleration?

Solving for Final Position with Constant Acceleration v = v 0 + a t . v = v 0 + a t . v 0 + v 2 = v 0 + 1 2 a t .

**Is velocity position as a function of time?**

Instantaneous velocity is a continuous function of time and gives the velocity at any point in time during a particle’s motion. We can calculate the instantaneous velocity at a specific time by taking the derivative of the position function, which gives us the functional form of instantaneous velocity v(t).

## How do you find the position of an object at time t?

The position of an object at time t is given by s(t) = -2 – 6t. Find the instantaneous velocity at t = 2 by finding the derivative.

**What is meant by function of time in physics?**

Anything that changes predictably over time, and can be represented by a mathematical equation, can be called a function of time. A moving object changes position over time. If it changes in a mathematically predictable way then the position can be said to be a function of time.

### What does time function mean?

This refers to a physical quantity which depends on time (and perhaps other parameters). For example, the temperature of a body undergoing a cooling process is a function of time.

**What is a function of time in physics?**

2) The following are functions of time: s(t) = distance a particle travels from time 0 to t. v(t) = velocity of a particle at time t. a(t) = acceleration of a particle at time t.

## What is the formula of time?

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

**Which of these terms means the change in position of an object with time?**

Change in position of an object with time is called MOTION . In simple words, an object is said to be in motion when it is not stationary.

### What is the function of time?

**How do you find position as a function of time?**

The position of an object as a function of time is given by x(t) = at3 − bt2 + ct − d where a=3.6 m/s^2, b=4.0 m/s^2, c=60m, and d=7.0m, how do you find instantaneous acceleration at t=2.4s?

## How do you determine the position of the object at t=0?

We say that the position of the object at t=0 is given, call it . Then at t=0 eq. 3.13becomes . So now we know D. It’s just . Plugging this back into eq. 3.13gives So if you know the initial position, the initial velocity, and the acceleration, then you can determine the position of the object as a function of time.

**What does the derivative of the position function tell you?**

Taking the derivative of the position function gives you the velocity of an object moving in a straight line, assuming there isn’t any air resistance. To put this another way, the velocity of an object is the rate of change of an object’s position, with respect to time. Let’s say an object has a position function f = s (t), where:

### What is an example of position function?

For example, the following graph of a position function tells you (in meters) where a car will be in the first few seconds after its start: Position function of a car. An object’s position is always relative to a location.
