Problem 3CQ

An object moves in a straight line at a constant speed. Is it true that there must be no forces of any kind acting on this object? Explain.

Step-by-Step Solution:

Step-by-step solution Step 1 0f 1 When an object is moving in straight line with constant speed many forces acting on it, they are 1.constant force 2.weight 3.reaction force 4.friction force 5. Resistance force 1. Constant force ; it acts on the body in the direction of motion of body and which helps to body to move with constant speed 2. Weight;it acts always down word vertically on the surface of moving object. weight=mg Where M is mass of the body. g is acceleration due to gravity M is constant. But g varies, so weight of the body is different in different planets. 3. Reaction Force: this is an upward force acts on the body which is equal to the weight. 4. Friction Force: the force which acts between the two surfaces . in the above case the friction force is acting between tyres and road. If the road is smooth, then frictional force is less vehicles moves easily. if the road is rough, then the friction force is more than it reduces the speed of the vehicle. 5. Resistance Force: the air opposes the motion of the vehicle i.e air resistance force. Always it acts opposite to the motion of object.
