Ou whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion. Which of the following is true for this situation? (Select all that apply.) The magnitude of the stone's velocity does not change. The direction of the stone's velocity changes as it moves around the circle. The stone's speed is constant. The change in direction of the stone's motion is due to the centripetal force acting on the stone. The stone is moving with constant velocity. Incorrect: Your answer is incorrect.

The magnitude of the stone's velocity does not change.

The direction of the stone's velocity changes as it moves around the circle.

The stone's speed is constant.

The change in direction of the stone's motion is due to the centripetal force acting on the stone.

The uniform motion of the stone around circular curve is directed inwards due to the centripetal force acting on the stone, keeping the stone moving in the circular path without falling off.

where;

From the formula given above we can conclude that;

The magnitude of the stone's velocity does not change.

The direction of the stone's velocity changes as it moves around the circle.

The stone's speed is constant.

The change in direction of the stone's motion is due to the centripetal force acting on the stone.

Explanation:

When a stone moves along a circular path, the magnitude of its velocity remains the same but the direction of this velocity changes. The direction of the velocity at any point is the tangent to the circular path at that point. The speed of the stone at any point along the circular path is constant since speed is a scalar quantity.

Centripetal force is the force that keeps the stone moving along its circular path.

The velocity of this stone changes even though the magnitude of velocity does not change. The velocity is said to change because its direction changes.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
