By observing the motion of objects on an inclined plane ______ deduced that objects move with a constant speed when no force acts on them.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Galileo.
- By observing the motion of objects on an inclined plane, Galileo Galilei deduced that objects move with a constant speed when no force acts on them.
- Galileo's experiments with inclined planes were crucial in developing the concept of inertia, which states that an object will remain at rest or move with constant velocity unless acted upon by an external force.
- This concept laid the foundation for Newton's laws of motion and had a profound impact on the development of classical mechanics.
