When the speed of an object is doubled what happens to the acceleration?

'F' = net force, 'm' = mass of the object, 'a' = acceleration F = m a a = F/m ==> This says that the acceleration is proportional to the net force. So if the net force is doubled, the magnitude of the acceleration also doubles, and it remains in the same direction as the net force.

∙ 15y agoThe speed of a car is 150 mph. so its in the 100's place (for homework) im only 10 years old thxxxx ppl bye

∙ 14y agoIf mass is doubled when applied force is kept constant, acceleration is halved. F = ma m = F/a (this rearragement shows the inverse relationship between mass and acceleration)

Given v = 2v and r = r/2
So new F = m x 8v 2/ r
Hence the new force would become eight times fold.

What happens to the speed of a moving object when it is doubled?
Acceleration is doubled. F = ma, where m is mass and a is acceleration. If mass is halved, acceleration is changed by a related quantity, X in this equation. F = (1/2m)(Xa) The coefficients before mass and accelerations have to equal 1 if force stays the same, so... 1/2*X=1 X = 2 therefore, acceleration is doubled.
What is the difference between an object with constant acceleration and an object with constant speed?
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
It is the velocity that increases.

Mass of an object is doubled at what speed?
Mass will be doubled if the speed is 31/2/2 times the speed of light.
How are velocity and acceleration different?
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
Is it possible for an object to have an acceleration when the speed of the object is constant?
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
When the mass of a moving object is doubled and its speed remains the same its momentum?
If the mass is doubled,speed should be halved to conserve momentum.
Can a object with no acceleration be stationary?
If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.
What happens if an object covers equal distances in equal periods of time?
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
