... momentum of the two-cart system is zero, even when the carts are in motion. Momentum is a vector, so the momentum of one cart is cancelled by the momentum of the other cart. Step 2 - If we double the mass of one of the carts and repeat the experiment, is momentum conserved? Yes, the momentum of this ...

Force and mass determine acceleration.
... Suppose the male skater shown above spins his partner faster. Her direction changes more quickly than before, so she accelerates more. To get more acceleration, he must apply more force. The same idea holds for a ball you whirl on a string. You have to pull harder on the string when you whirl the ba ...

Chapter 4: Forces and Newton`s Laws of Motion
... The free body diagram (FBD) is a simplified representation of an object, and the forces acting on it. It is called free because the diagram will show the object without its surroundings; i.e. the body is “free” of its environment. We will consider only the forces acting on our object of interest. Th ...

Center of mass
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. Calculations in mechanics are often simplified when formulated with respect to the center of mass.In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.
