Which Describes What A Velocity Time Graph Would Look Like With No Acceleration?

Which explains what a velocity time graph would look like with no acceleration?

With no acceleration, the “velocity” is constant …

the speed isn’t changing and the direction isn’t changing.

A so-called “velocity/time” graph is really just a “speed/time” graph, because it doesn’t show any information about the direction of motion.

So the graph never gets any higher or lower..

Is speed the same as velocity?

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

What does it mean when velocity is 0?

This is because veloctiy is the rate at which an object changes position. If you walk from here to there (doesn’t matter where), and go back here from there (exactly at the same spot) when 5 minutes has passed, then in 5 minutes your velocity is zero because there is no change on your displacement.

Can a body have acceleration with zero velocity?

Yes, an object can have zero velocity and still be accelerating simultaneously.

How is velocity calculated?

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

What is the difference between speed and velocity and acceleration?

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.

Does 0 velocity mean 0 acceleration?

Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

Why is acceleration not zero when velocity is zero?

The object has a velocity towards the ground, but due to a force in the opposite direction, the object decelerates to zero. At zero velocity, there is still a net force acting on the object due to the spring, so the object will accelerate in the opposite direction. … Acceleration a is constant and thus a(t)=−g.

What happens to the velocity if acceleration is zero?

Constant velocity means the acceleration is zero. The change in velocity over a certain time interval equals the area under the acceleration graph over that interval. In this case the velocity does not change, so there can be no area under the acceleration graph.

What does acceleration look like on a velocity time 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).

Which describes what a velocity time graph?

Speed-time graphs are very useful when describing the movement of an object. … The area under a speed-time graph represents the distance travelled. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area of the velocity time graph.

Which graph shows a negative acceleration?

The velocity-time graph shows a line with a negative (downward) slope (negative acceleration); the line is located in the positive region of the graph (positive velocity).
