Solution
An object that is moving at constant speed (uniform speed) has both resultant/net forces and resistive forces acting on it.
Here's why:
-
When an object is moving at a constant speed, it means that it is not accelerating or decelerating.
-
According to Newton's first law of motion, an object will continue to move at a constant speed in a straight line unless acted upon by an external force.
-
In this case, the external forces acting on the object are balanced, meaning that the resultant or net force is zero.
-
However, even though the net force is zero, there are still forces acting on the object. These forces are known as resistive forces, which include things like friction and air resistance.
-
These resistive forces are balanced by other forces acting on the object, such as the force of gravity and the normal force (the force exerted by a surface that supports the weight of an object).
-
Therefore, an object moving at a constant speed has both resultant/net forces (which are zero) and resistive forces acting on it.
