Is it possible to have motion in the absence of a force group of answer choices?
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 direction and speed in the absence of a force. These are all external forces acting on the object.
Is net force necessary to maintain the state of motion?
depends on the speed. If an object is in motion, then it will stay in motion with those very same motion characteristics. It doesn’t take any force to maintain that same state of motion. In fact, the presence of a force would “ruin” such a state of motion and cause an acceleration.
Can an object be moving with a net force of 0?
Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it.
Can an object be at rest but has non zero acceleration acting on it?
Finding the acceleration Thus, even though the velocity of an object at rest must be zero, acceleration can clearly be non-zero for objects at rest. A particle that is thrown vertically upwards stops momentarily at the highest point of motion.
Can an object maintain uniform velocity when its acceleration is not zero?
Explanation: No its is not possible for an object to maintain uniform velocity if acceleration is not zero. While it is possible when a body is present in uniform speed.
Why is a body having uniform velocity has zero acceleration?
It measures how much velocity is changing in a given time interval. If the body has uniform velocity, it means velocity is not changing. So the change in velocity is zero. In other words, its acceleration is zero.
When an object is moving at a uniform velocity does it need a force to maintain its uniform state of motion justify your answer?
No. By →F=m→a if there is no change in velocity (i.e. the velocity is uniform) then →a=0 and thus the net force →F=0.
Is uniform motion a balanced force?
An object moves with a uniform velocity when the forces (pushing force and frictional force) acting on the object are balanced and there is no net external force on it. If an unbalanced force is applied on the object, there will be a change either in its speed or in the direction of its motion.
