Plzzz HELP MEEEE.
A net force is applied to a moving object. Which statement best describes the effect of the force?(1 point)

A. The force will cause a change in the direction of the object.
B. The force will cause the object to come to a stop.
C. The force will cause the speed of the object to increase.
D.The force will cause a change in the momentum of the object.
I WILL GIVE BRAINLIEST TO THE ONE WITH THE BEST ANSWER.... PLEASEEEE HELP....

Respuesta :

Answer:

I would say D:  a change in the object's momentum.

Explanation:

A. The force will cause a change in the direction of the object.  Not necessarily.  If the net force were in the same direction as the moving object, then no.  Pass.

B. The force will cause the object to come to a stop. Not necessarily.  If the net force were in the opposite direction as the moving object and was removed after the object stops, yes.  But this is not defined, so no is the safer answer.  Pass.  

C. The force will cause the speed of the object to increase.  Again, it depends on the direction, magitude, and duration.  No - pass.

D.The force will cause a change in the momentum of the object.  Yes - best answer.  All it is stating is "something is gonna happen."  Yep, that's my choice.  We don't need to predict what or how much, but something will happen.  Check.

When a net force is applied to a moving object it will cause a change in the speed of the moving object which will further cause a change in momentum of the object.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object. The object tends to move in the direction of the applied force or net force.

∑F = ma

The net force acting on a moving object will cause a change in the speed of the object, which will in turn cause a change in the momentum of the object.

ΔP = mΔv

where;

  • ΔP is change in momentum
  • Δv is change in speed

Thus, we can conclude that when a net force is applied to a moving object it will cause a change in the speed of the moving object which will further cause a change in momentum of the object.
