Speed is relative to the speed of light and gravity. So gravity could effect speed.
Friction will reduce an object's speed.
applying a force to an object, (pushing, pulling, hitting, kicking etc.) can change its speed, its direction and its shape.
Friction acts to oppose the motion of an object, reducing its speed over time. The direction of friction force always opposes the direction of the object's motion, causing it to slow down.
Assuming that the force is great enough to overcome static friction; the force will change the momentum of the object.
Yes, an object can move at a constant speed if the three forces acting on it are balanced, resulting in zero net force. The forces can cancel out each other's effects, allowing the object to maintain a constant speed.
The force can change the speed of the object by either speeding it up or slowing it down. The force can also change the direction of the object's motion, causing it to turn or move in a different path.
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.
there are not 4 but 3 effects of electric current - heating effect, magnetic effect and chemical effect of electric current

WHAT THE SPEED OF STATIONARY OBJECT?
Well... if something changes, it can't be called a constant. And the effects appear not at the speed of light, but when you approach it. What changes is: the time; distances in the direction of travel; the mass of the travelling object.
If operating in free space, the speed of the object will be constant. If not operating in free space, but under the effects of gravity, then apply gravitational formulas to find the answer.
