2. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   The "natural" motion of terrestrial solid matter was to fall downwards, whereas a "violent" motion could push a body sideways. Moreover, in Aristotelian physics, a "violent" motion requires an immediate cause; separated from the cause of its "violent" motion, a body would revert to its "natural" behavior.

3. Force - Wikipedia

   en.wikipedia.org/wiki/Force

   In such a situation, a force is applied in the direction of motion while the kinetic friction force exactly opposes the applied force. This results in zero net force, but since the object started with a non-zero velocity, it continues to move with a non-zero velocity. Aristotle misinterpreted this motion as being caused by the applied force.

4. Motion - Wikipedia

   en.wikipedia.org/wiki/Motion

   The branch of physics describing the motion of objects without reference to their cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. If an object is not in motion relative to a given frame of reference, it is said to be at rest , motionless , immobile , stationary , or to have a constant ...

5. Coriolis force - Wikipedia

   en.wikipedia.org/wiki/Coriolis_force

   In physics, the Coriolis force is an inertial (or fictitious) force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object. In one with anticlockwise (or counterclockwise) rotation, the force ...

6. Reaction (physics) - Wikipedia

   en.wikipedia.org/wiki/Reaction_(physics)

   The case of any number of forces acting on the same object is covered by considering the sum of all forces. A possible cause of this problem is that the third law is often stated in an abbreviated form: For every action there is an equal and opposite reaction, [8] without the details, namely that these forces act on two different objects ...

7. Newton's law of universal gravitation - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_universal...

   Newton's law of gravitation resembles Coulomb's law of electrical forces, which is used to calculate the magnitude of the electrical force arising between two charged bodies. Both are inverse-square laws, where force is inversely proportional to the square of the distance between the bodies. Coulomb's law has charge in place of mass and a ...

8. Bouncing ball - Wikipedia

   en.wikipedia.org/wiki/Bouncing_ball

   The forces acting on a spinning ball during impact are the force of gravity, the normal force, and the force of friction (which has in general both a 'translational' and a 'rotational' component). If the surface is angled, the force of gravity would be at an angle from the surface, while the other forces would remain perpendicular or parallel ...

9. Centrifugal force - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_force

   In the reference frame of the spinning masses, centrifugal force causes the radial movement. A centrifugal clutch is used in small engine-powered devices such as chain saws, go-karts and model helicopters. It allows the engine to start and idle without driving the device but automatically and smoothly engages the drive as the engine speed rises.
