A box is against a wall. A person pushes on the box, but the box does not move. Is this situation an example of a force?(1 point)
Responses
No, this is not an example of a force because a force pulls an object.

The correct response is:
**They have the same speed but different velocities.**
Although Matt and Jaime are both walking at the same speed of 1.25 miles per hour, their velocities are different because velocity includes both speed and direction. Matt is walking east, while Jaime is walking south, so their velocities differ in direction.

The correct response is:
**The object remains still.**
A horizontal line on a position-time graph indicates that the position of the object is not changing over time, meaning the object is stationary (remains still).

The correct response is:
**a force applied in the opposite direction with a greater magnitude at the same time.**
If a force acts on an object and another force of greater magnitude is applied in the opposite direction, it will result in a net force that can prevent the object from moving or even cause it to move in the direction of the stronger force.

The correct response is:
**the force needed to lift a chair.**
Among the options given, lifting a chair typically requires the greatest force compared to lifting a pencil, a hairbrush, or a textbook, as chairs generally have more mass than those other objects.

The correct response is:
**Yes, this is an example of a force because a force is a push or pull.**
Even though the box does not move, the person is applying a force by pushing on it. A force is defined as any push or pull exerted on an object, regardless of whether the object moves in response to that force.
