A skater is coasting alone the ice without sexerting any apparent force. Which law of motion explains the skater's ability to continue moving?
inertia?
thankyou
The skater's ability to continue moving without exerting any apparent force is explained by Newton's First Law of Motion, also known as the law of inertia. This law states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force.
In this case, once the skater pushes off or receives an initial force to start moving, there is minimal friction between the skates and the ice, so no significant external force acts to slow the skater down. As a result, the skater will continue coasting along the ice in a straight line with a constant velocity until an external force, such as pushing against the ice or encountering friction, is applied to change their motion.
