* Constant speed means the object is not accelerating.
* Acceleration is caused by a net force (the sum of all forces acting on an object).
* Therefore, if the net force is zero, the object will not accelerate and its speed will remain constant.
Example:
Imagine a box being pushed across a floor. Here are the forces acting on it:
* Force 1: The force you apply to push the box.
* Force 2: The force of friction between the box and the floor.
* Force 3: The force of gravity pulling the box down.
If you push the box at a constant speed, the force you apply is equal and opposite to the force of friction. The force of gravity is balanced by the normal force from the floor. This means the net force is zero, and the box moves at a constant speed.
Key Points:
* Net force determines acceleration, not individual forces.
* A constant speed means zero acceleration.
* Forces can be balanced even if there are multiple forces acting on an object.
