The direction of a moving object will not change if the net force acting on it is

The direction of a moving object will not change if the net force acting on it is zero.

Explanation:

If there is a net force acting on a body, the body may accelerate, slow down, or change direction. In other words, an unbalanced net force may change the state of motion of a body.

The only way a moving object will not change its direction if the body is moving with a constant velocity, meaning all the forces acting on the body are in equilibrium (or balanced). In other words, the net force acting on it is zero, and the speed, as well as direction, would not change.

Therefore, we conclude that the direction of a moving object will not change if the net force acting on it is zero.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
