'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.
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.
Doubling the force acting on a moving object would cause the object to accelerate at a faster rate, leading to an increase in its speed. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
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.

The speed of an object does not change if only its mass is doubled. The speed of an object is determined by its velocity, which is independent of its mass. However, doubling the mass of an object will affect its momentum and kinetic energy.
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.

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".
The speed of an object can change over time due to various factors such as acceleration, deceleration, or forces acting on the object. In general, the speed of an object will increase if it is accelerating and decrease if it is decelerating.
If an object travels with zero acceleration, its speed remains constant. This means that the object maintains the same speed throughout its motion and does not change its velocity.
An object moving at a constant speed is not undergoing acceleration because acceleration is a change in velocity over time. Since the object's speed is not changing, there is no acceleration.
When velocity and acceleration are not in the same direction, the object's speed may be changing. If the acceleration and velocity are in opposite directions, the object will slow down. If they are at right angles to each other, the object will change direction without changing speed.
