What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculated by: a=(vf - vi) / t where a is acceleration vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero. Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
How do you find acceleration from speed?
If speed does not change, then acceleration is 0 To find acceleration, you must also know the time Speed = metres per second. Acceleration = meters per second, per second Therefore you can use the equation m/s2 to find the acceleration. change in speed/ change in time.
What does it mean if a line is flat on a distance-time graph?
Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?
If the velocity is constant (no acceleration), the net force is zero.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
What is acceleration of a rain drop that falls at a constant velocity?
If the velocity is constant then there is no acceleration. The acceleration is zero.
Is it possible for a body to have acceleration when moving constant speed and constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Can something have both a constant velocity and constant acceleration?
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.
Can an object traveling at constant velocity have acceleration why?
If a velocity or speed is constant there isn't an acceleration. This is because the acceleration is the change in speed or velocity and if it's constant then there sn't a change.
Why is constant velocity not acceleration?
Acceleration is the rate of change in velocity. When velocity is constant, it is NOT CHANGING so acceleration is negligible or ZERO or non-existent.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
