How much force is needed to keep an object moving?
It includes the law of inertia → if there is no force, F = 0, then the acceleration = 0 → the velocity doesn’t change → no force is needed to keep an object moving with constant velocity.
If there is more than one force acting on an object, then F is the net force..
What causes an object at rest to move?
For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest. … Speed tells us how fast something is moving.
Can sound make objects move?
Scientists have been able to use the power of sound to levitate small items — including insects and fish — for decades. Sound waves exert pressure when they hit a surface, but the effects are usually too small to notice. …
Can an object move by itself?
Of course, things don’t just move by themselves. An object must be pushed or pulled to get in motion. A force is a push or a pull. … The more force you use, the faster the object will move.
What if there is no motion?
If there is motion, there is a force acting. There cannot be a force without motion and if there is no motion, then there is no force acting. (for example, students see a downward force of a book acting on a table, but they do not see an upward force of the table acting on the book.)
Does time exist without motion?
Time can exist without motion. Time is not dependent on motion. It is motion that is dependent on time. But motion (in a clock or sun) does indicate the passage of time.
What is the force required to keep an object moving?
According to Galileo and Newton, when is a force needed to keep an object moving? Only when friction (or some other oppositional force) is present is a force needed to keep an object moving. The net force equals mass times acceleration.
What are the forces that acts on an object?

Can an object have motion without force?
Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…
What if I push an object which is already moving horizontally?
Thus, force would cause. acceleration in horizontal motion.
What happens when two objects collide?
Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
In which situation the box will accelerate more?
the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.
