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.

∙ 14y agoWhen the speed of a moving object is doubled, it takes on a numerical value that is
approximately equal to 2.000 times its original value. This relationship holds in both
the English and the SI system of units.

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.
What happens to the speed of a moving object when it decelerates?
It slows down.
What happens to the speed of moving object when it is pushed in the direction of motion?
The speed increases. The object accellerates positively in the direction of motion.
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
What happens to the speed of a moving object when it accelerates?
An object is accelerating if any of these things are happening . . .-- its speed is increasing-- its speed is decreasing-- its direction is changing.The object may be accelerating even if its speed isn't changing.Acceleration does not mean "speeding up".
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.
What happens to the speed of a moving object when it decelerates?
It slows down.
What happens to the speed of moving object when it is pushed in the direction of motion?
The speed increases. The object accellerates positively in the direction of motion.
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.
What happens to the speed of a moving object when it.decelerate?
Decelerate means to slow down.
What happens if a large mass is dropped into something moving at constant speed?
The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
What happens to the speed of a moving object when it accelerates?
An object is accelerating if any of these things are happening . . .-- its speed is increasing-- its speed is decreasing-- its direction is changing.The object may be accelerating even if its speed isn't changing.Acceleration does not mean "speeding up".
What happens to an object when the forces are balenced and it's moving?
Then the result will be the same as if NO forces act on the object (since the sum of the forces is zero). The object will continue moving in a straight line, at constant speed.
If an object accelerates in the same direction in which it is moving how is its speed affected?
The speed of the object will increase.
What happen to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
What happened to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
