Studied by 503 peopleWhat is rotational motion?
Rotational motion is the motion of an object around an axis or a fixed point.
What is linear kinematics?
Linear kinematics is the study of motion of objects in a straight line.
What is rotational kinematics?
Rotational kinematics is the study of motion of objects that rotate around a fixed axis.
What is force?
Force is a push or pull that can cause a change in motion.
What is torque?
Torque is the force that causes an object to rotate about an axis.
What is mass?
Mass is the amount of matter in an object.
What is moment of inertia?
Moment of inertia is the resistance of an object to rotational motion.
What is acceleration?
Acceleration is the rate at which an object changes its velocity.
What is angular acceleration?
Angular acceleration is the rate of change of angular velocity with respect to time.
What is the equation for Fnet?
Fnet = ma
What is the equation for Tnet?
Tnet = Ia
What is velocity?
Velocity is the speed and direction of an object's motion.
What is angular velocity?
Angular velocity is the rate of change of angular displacement with respect to time.
What is angular displacement?
Angular displacement is the angle through which an object rotates.
What is the relationship between linear and angular motion?
The linear velocity and acceleration of a point on a rotating object are equal to the product of the angular velocity and acceleration and the radius of the circle.
What is center of mass?
Center of mass is the point in an object or system that moves as if all the mass were concentrated at that point.
What is the formula for calculating center of mass?
COM = (m1r1 + m2r2 + ... + mn rn) / (m1 + m2 + ... + mn)
What is the right-hand rule?
The right-hand rule is a rule used to determine the direction of torque.
What is the formula for torque?
τ = r x F
What is the unit of torque in the US customary system?
The unit of torque in the US customary system is the foot-pound (f
