Torque and Rotation

Torque and Rotation. Physics. Torque. Force is the action that creates changes in linear motion. For rotational motion, the same force can cause very different results. A torque is an action that causes objects to rotate.

FORCE is a vector quantity which can cause an object to change its shape

FORCE is a vector quantity which can cause an object to change its shape (ie., become deformed). And, for every force, there is an equal and opposite force!! Check out the equal and opposite forces exerted on the ball and the

Rotational Equilibrium & Dynamics

Rotational Equilibrium & Dynamics. 8-2: Equilibrium & Center of Mass. Question. There is a point on a broom (or any extended object) at which it will balance perfectly. If you cut the broom at that point and weigh each part of the broom, what would you find?. Equilibrium.

Forces and Dynamics

Forces and Dynamics. Equilibrium of Forces. Equilibrium of Forces Translational Equilibrium If every part of a system moves in a straight line at a constant speed, we say it is in translational equilibrium. This includes being at rest.

ROTATIONAL MOTION

ROTATIONAL MOTION. Sec. 7.4 Torque, Equilibrium & Stability. ROTATIONAL MOTION. This motion is related to circular motion except the object is rigid. It deals with the spin of an object, not the linear motion! Torque : measures the ability of a force to rotate an object around some axis.
