wiki Word: constant speed due to balanced forces

Definition: When an object is moving so that its instantaneous speed is always the same because the forces around it are balanced and are not causing change.

When an object is moving at a constant speed, the speed is not changing. The speed is not changing because the forces around the object are balanced. When forces are balanced they will not cause any change because the forces are equal in the opposite direction.

      Constant speed applies to our class because we used constant speed in one or more of our labs. When we constructed air rocket cars we had to measure the time it took for the car to pass a certain benchmark. Using the time and distance we found the speed by dividing distance  by time. Most of the cars didnt have a constant speed because there were unbalanced forces that were affecting the car. An example of an unbalanced force would be a clump of dirt that the car may bump in to,  which would either slow the car down or completely stop it. If there were no unbalanced forces acting on the car it would have moved at a constant speed. Knowing abou tconstant speed is very useful in real life situations.
