Question

When an object moves, stops moving, changes speed, or changes direction, how do scientists describe that condition?

A.
stable factors

B.
frictional force

C.
a balanced set of forces

D.
unbalanced forces

Answer 1

if its an inertial frame of reference(meaning it is observed by someone not accelerating) then this would be the result of unbalanced forces

Answer 2

like say your car is moving forward, and you turn the car to reverse mode.. and start decelerating, it will still keep moving until it stops and changes direction and moves the other way, it was all caused by a force the car exerted in the opposite direction of motion

Answer 3

unbalanced force.

An object at rest will remain at rest until acted upon by a force.

An object in motion will remain in motion until acted on by a force.

imagine you and a friend pull a rope tug of war style. If you and your friend pull with the exact same force [balanced forces, equilibrium] the rope stays exactly where it is.
If one of you gets tired and the other pulls harder, the forces become unbalanced and the rope moves

Answer 4

i agree unbalanced force!
