True or False: According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by an unbalanced force.
True.
True. According to Newton's first law of motion, also known as the law of inertia, an object at rest will remain at rest unless acted upon by an unbalanced force. Similarly, an object in motion will continue to move at a constant velocity in a straight line unless acted upon by an unbalanced force.
True. According to Newton's first law of motion, also known as the law of inertia, an object at rest will remain at rest unless acted upon by an unbalanced force.
To understand this principle, we can break it down into two parts.
First, an object at rest means that it is not moving. In other words, its velocity is zero. This could be a stationary object on a table, for example.
Second, the law states that unless an unbalanced force acts upon the object, it will remain at rest. An unbalanced force is a force that causes a change in the object's velocity. If there is no net force acting on the object, it will maintain its state of rest.
For example, imagine a book sitting on a table. The force of gravity pulls the book downwards, but the table exerts an equal and opposite force called the normal force, effectively balancing out the downward force. As a result, the book remains at rest and does not move.
It's important to note that if there is a balanced force acting on an object at rest, it will not move either. Only an unbalanced force will cause a change in the object's motion.
