What else can I help you with?
What happens to a system when there are no external forces acting on it?
If there are no external forces acting on a system, it will remain in its current state of motion or rest. This is described by Newton's first law of motion, which states that an object will continue in its state of rest or uniform motion in a straight line unless acted upon by an external force.
How do you tell if a book is at rest or in motion?
A book is at rest if it is not moving relative to a reference point. If the book is changing its position relative to the reference point, then it is in motion. In physics, rest and motion are relative to the observer's frame of reference.
When a book falls off the table it changes into what?
When a book falls off the table, it changes from a state of rest to a state of motion. Gravity is the force acting on the book that causes it to fall.
What happens to an object when there is no force acting on it?
If there is no external force acting on an object, it will continue to move at a constant velocity or remain at rest, according to Newton's first law of motion. This is also known as the law of inertia.
What happens to a object if there are no forces acting upon it?
If there are no forces acting on an object, it will remain at rest or continue moving at a constant velocity in a straight line, as per Newton's first law of motion.
What happens if the forces acting on a object are balanced?
If the forces acting on an object are balanced, it means that the net force on the object is zero. In this case, the object will either remain at rest if it was initially at rest, or it will continue to move with a constant velocity if it was already in motion.
Objects at rest or in uniform motion have what acting on them?
zero net force
A moving object with no forces acting on it will?
Continue to move along its path. "An object in motion tends to stay in motion and an object at rest, tends to stay at rest."
If there is no force acting on an object it will what?
If there is no force acting on an object, it will remain in its state of motion (either at rest or moving at a constant velocity) according to Newton's first law of motion.
Examples of inertia of rest and inertia of motion?
Inertia of rest is the tendency of an object to remain at rest when no external force is acting on it, like a book staying on a table. Inertia of motion is the tendency of an object in motion to remain in motion at a constant velocity in a straight line, like a car continuing to move forward once the brakes are released.
What kind of object has constant velocity?
An object at rest or in motion with no force acting upon it.
Why does a book continue to move forward when a car stops?
The book is experiencing inertia; a state which resists change in motion. This is represented by Newton's first law of motion which states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an external force. Therefore the book in the car continues to move forward until it is acting on by an external force such as the applied force of something in the book's path of motion.
