What happens if velocity is constant?

What happens if velocity is constant?

Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its trace over time.

Can a particle with constant speed be accelerating what if it has constant velocity?

A particle with constant speed can be accelerating, if its direction is changing. However, a particle with constant velocity cannot be accelerating — its acceleration must be zero. It has both constant speed and constant direction.

Can a body have acceleration If velocity is constant?

And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating.

Can a body have constant speed and still be accelerating?

(i) A body can have acceleration even when it has uniform speed. A body in uniform circular motion has uniform speed but at every point its direction of velocity changes, so its motion is accelerated. (ii) Yes, a body can have acceleration even when its velocity is zero.

What keeps things in circular motion?

Specifically, you have centripetal acceleration — the acceleration needed to keep the object moving in circular motion. The centripetal acceleration always points inward along the radius toward the center of the circle. At any point, the velocity of the object is perpendicular to the radius of the circle.

What is the slope of an acceleration time graph?

The slope of an acceleration graph represents a quantity called the jerk. The jerk is the rate of change of the acceleration.

What is the slope of position vs time graph?

The slope of a position-time graph represents velocity. The steeper the slope is, the faster the motion is changing. Average velocity can be calculated from a position-time graph as the change in position divided by the corresponding change in time.

What does the slope of a distance-time graph show?

In a distance-time graph, the slope or gradient of the line is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving. Calculate the speed of the object represented by the green line in the graph, from 0 to 3 s.

How will you show the slope of displacement time graph gives velocity of the body?

Answer Expert Verified In Displacement time graph, the time is taken on X axis and displacement on y axis. The slope of displacement time graph gives velocity. Since velocity= displacement/ time.

What is the shape of distance-time graph for a stationary object?

It is a graph obtained by plotting distance travelled along Y-axis and time taken along X-axis. (i) Distance-time graph for stationary body: The position of a stationary body does not change with time. So distance-time graph for a stationary body is a straight line parallel to time axis, as shown in Fig.

What will be the shape of the distance time graph if unequal distance is covered in equal intervals of time?

Answer. The distance-time graph would be a jagged line because it symbolises non-uniform motion.

What is distance time graph 7?

Class 7 Physics Motion and Time. Distance-Time Graph. Distance-Time Graph. This is usually drawn as a line graph as it taken two variable quantities – Distance and Time. In a Distance-Time graph, Distance is considered on the Y-axis (Vertical) and Time is considered on the X-axis (Horizontal).

What will be the graph for non-uniform motion?

A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time. The distance-time graph of the non-uniform motion is a curved line. Non-Uniform motion is also known as accelerated motion.

What is the difference between uniform and nonuniform motion draw a distance time graph in both cases?

Non-uniform motion refers to the motion where the body covers unequal distances in equal intervals of time . The graph is a curve shown in the attachment. Uniform motion refers to the motion where the body covers equal distances in equal intervals of time . The graph is a straight line .
