Question

Galileo concluded that an object moving on a frictionless horizontal surface should move with constant velocity.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation:

1. According to Newton's 1st law, states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
2. When an object moves over a rough surface and it offers frictional force in the opposite direction of motion.
3. Due to this opposition object stop after covering a certain distance.
4. Thus when an object moves along a frictionless surface there is no opposition and no unbalanced force acts on it, so it will move uniformly.

Hence, the given statement is True.
