Raindrops fall in the direction of gravity, which is typically straight down. However, during a heavy shower, wind can cause raindrops to fall at an angle or be blown sideways. The shape, size, and weight of raindrops also play a role in determining their direction of fall.
An external force is a force that causes a change in an object's motion by pushing or pulling it in a certain direction. This force can accelerate, decelerate, or change the direction of the object's movement.
REFRACTION
True. When radar energy is returned, it can provide information on the direction and speed of raindrops. By analyzing the Doppler shift of the returned signal, meteorologists can determine the speed at which raindrops are moving towards or away from the radar site.
The change in speed of light changes the direction.
A force.
work
If a change in the body causes more change in the same direction, the system is called positive feedback. This feedback loop amplifies the initial change and pushes the system further away from its original state.
gravity (up to down) friction
A change in velocity due to a change in direction in a space shuttle is caused by the application of thrust from its engines. By adjusting the direction of thrust, the shuttle can alter its velocity vector, changing its speed and/or direction of travel. This allows the shuttle to adjust its course, orbit, or perform maneuvers in space.
