Concept explainers
The forces are acting on a car that is moving in a straight line with constant speed or not.
Explanation of Solution
Introduction:
The algebraic sum of all the forces represents the net force acting on an object. The net force is accountable for developing the acceleration in the object.
When a car moves in a straight line with constant speed, the force of inertia (air resistance), friction force and weight act on the car. Since, the car is moving in astraight linewith the constant speed, so, the acceleration will be zero and the inertia force becomes zero. Thus, only weight and friction force will act on the car.
Conclusion:
Therefore, there can be forces acting on a car that is moving in a straight line with the constant speed.
