'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.
The speed of a car is 150 mph. so its in the 100's place (for homework) im only 10 years old thxxxx ppl bye
If 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)
Centripetal force F =m x v2/r
Given v = 2v and r = r/2
So new F = m x 8v 2/ r
Hence the new force would become eight times fold.
It will also double, according to Newton's Second Law.
Acceleration is the change of velocity per unit time. Once the object has a constant velocity, its acceleration will be zero.
Then its acceleration also doubles.

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.
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.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Acceleration is zero when the object's speed and direction stop changing.

Mass will be doubled if the speed is 31/2/2 times the speed of light.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Acceleration is zero when the object's speed and direction stop changing.
Acceleration is negative.
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
If the mass is doubled,speed should be halved to conserve momentum.
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.
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.
