Is the rate of change of acceleration with time important to describe the motion of the body?

The rate of change of acceleration with time of a body is not important to mechanics. It is because, the basic laws of motion only involve acceleration, whereas as the quantity: rate of change of acceleration is not required at all.

What is important to describe the motion of a body?

Answer: You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing.

How do you describe acceleration on a graph?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

What conclusion do you draw about acceleration of the particle in motion from given velocity time graph?

Answer: Explanation: The particle is travelling with uniform or constant velocity which means there is no change in velocity, which in turns means that the object has no acceleration.

What best describes what occurs when a body accelerates?

Which BEST describes what occurs when a body accelerates? Change in velocity per unit time.

How do you describe motion on a distance time graph?

If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

Why does acceleration increase over time?

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction.

How do you describe the motion of a velocity time graph?

A velocity-time graph shows the changing velocity of the sprinter or of any other moving person or object. In a velocity-time graph, acceleration is represented by the slope of the graph line. If the line slopes downward, like the line between 7 and 10 seconds, velocity is decreasing and acceleration is negative.

How do you describe motion on a position time graph?

In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. The position of the object is not changing. The steeper the line is, the greater the slope of the line is and the faster the object’s motion is changing.

Why is the motion in a circle at constant speed called accelerated motion?

Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves at a constant speed, its velocity is not constant. Therefore, circular motion is an acceleration motion even when the speed remains constant.
