... An object that is at rest will remain at rest and an object that is moving will continue to move in a straight line with constant speed, if and only if the sum of the forces acting on that object is zero. Newton's 2nd Law acceleration of an object = sum of forces acting on that object / the mass of ...

... The moveable pulley offers a mechanical advantage even though it does not change the direction of effort. The load is supported by rope on both sides of the pulley, which means that half as much effort is needed to lift the load. You must exert effort twice as far as the load moves. The force needed ...

... – Isobars plotted on a surface weather map are almost always curved; the wind blows in curved paths. Curved motion indicates the influence of the centripetal force. – Center-seeking force; the string exerts a net force on the rock by confining it to a curved path – Increasing the rotation rate or sh ...

... This force applied over a time interval is called impulse, I, and equals the change in momentum during that time interval. Since impulse only depends on velocity and mass, and is independent of the impact surface, the impulse (area under the force-time curve) will be constant (for a given kinetic en ...
