If all of the forces on an object are balanced, then their net effect on the object
is the same as if there were no force on it at all. Under those circumstances, its
acceleration is zero, meaning that its speed and direction of motion do not change.

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.
When a lorry is moving at a constant speed what force on the lorry are balenced?
The forces are:Drag and Friction
What three forces affect speed?
The three forces that affect speed are thrust (what propels the object forward), surface area (the smoothness and amount of area that comes in contact with the air, which can also be called friction), and drag.
Does the mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does an unbalanced force affect a moving object at a constant velocity?
If the group of forces on an object is unbalanced, then the object can't have constant velocity. Its speed or the direction of its motion must change.
How does friction affect interia?
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
How does the height of a ramp affect the speed of a rolling object?
At the bottom of the ramp, the higher the ramp the faster the speed, ignoring frictionl forces The speed varies as the square root of the height
Why does gravity affect speed?
Because the effect of gravity is to cause forces between every two objects that have mass, and force on an object generally affects its speed.
Which of these would change the direction of an object but not affect the object's speed?
Circular motion would change the direction of an object but would not affect the object's speed.
What forces can affect an objects velocity but not the speed?
Centripetal forces can.
Increasing the speed of an object does not affect that object's what?
mass
