This fake force will be equal to the mass of the arrow multiplied by the acceleration of the frame---but in the opposite direction of the frame's acceleration. Don't worry about these fake forces ...

The arrow shows the direction. The length of the arrow ... Earth pulls the satellite and the satellite pulls Earth. The forces are equal in size and opposite in direction. A skydiver is falling ...

One of the more curious challenges in physics is to understand the nature of time. At the microscopic level, the laws of physics are symmetric with respect to time—they work just as well whether ...

In a force diagram, an arrow represents each force ... The forces on this hanging crate are equal in size but act in opposite directions. The weight pulls down and the tension in the rope pulls ...

The engine burns fuel, which is accelerated toward the rear of the ship. This causes a force in the opposite direction to push the rocket forward. Thrusters can also be used on the sides of the ...
