Since the car maintains a constant velocity, there’s no additional force acting on the ball while it’s airborne. Therefore, the ball travels vertically upward after being thrown and then falls straight back down relative to the car’s frame of reference. ...
The synchronizing satellite rotates around the Earth in a West to East direction. This rotation synchronizes with the Earth’s rotation, facilitating stable positioning relative to a point on the Earth’s surface. This alignment is essential for functions such as communication ...
The function of the ball bearing in the wheel is to convert static friction into kinetic friction. This conversion allows for smoother rotation by reducing resistance between moving parts. Ball bearings facilitate efficient motion and are crucial components in various ...
The water level remains the same when the ice cube melts. This is because a floating object displaces an amount of water equal to its own weight. Since water expands when it freezes, the volume of the melted ice cube ...
