An object with acceleration of 0 will stay still if it starts of still or will keep going at the speed it started with. This question has a lot to do with Newton's first law of motion. Newton's first law says something like an object (ball, car, spaceship, anything) remains at rest or continues to travel at a constant speed unless acted upon by an external force.
An object at a constant velocity (or motion) has a overall force of 0.
The bus is in steady motion along a straight line at a constant velocity.
the net force which is the vector sum of the forces. If that sum = 0 then no motion occurs
An unbalanced force produces a change in motion which means an object moves. In balanced forces, the net force is 0 and the object does not move.
Newton's first law basically says that an object in motion that is not acted on by any other forces will stay in motion and an object at rest that is not acted on by any other forces will stay at rest. An example of an object in motion staying in motion could be an astronaut floating in outer space. As long as there is no gravity force acting on him (and there is no drag because space is a vacuum) the astronaut will continue to float at the same speed and in the same direction forever.
An object at a constant velocity (or motion) has a overall force of 0.
Nothing happens to its motion, and it continues moving in a straight line at constant speed.
The bus is in steady motion along a straight line at a constant velocity.
the net force which is the vector sum of the forces. If that sum = 0 then no motion occurs
0 velocity 0 acceleration The forces on the object are balanced: it is in equilibrium. (The forces are balanced on any object with 0 acceleration, even if it is moving.)
His First Law and Second Law both do.
An unbalanced force produces a change in motion which means an object moves. In balanced forces, the net force is 0 and the object does not move.
it will be in the same direction in which it is moving. If it is not moving it will remain at rest
The motion of an object will change when a force is applied to it. Newtons laws of motion descibe this. An object without any force being aplied to it will remain at constant velocity. Wether that be at a constant 0 m/s or a constant 12m/s or 300 m/s and so on. The motion of that object will change when a force is applied to it by causing an increase in acceleration in the direction of the force being applied. -look up Newtons Laws of motion for more detail.
You could say that its motion is uniform, meaning that its speed is constant,and that it's moving in a straight line.
According to newtons second law of motion when the net force on an object is greater than 0, F=m*a where a is the acceleration, m is the mass, and F is the force.
