Impulse and Momentum

Impulse Noun

---

[im-puls]

• The total effect of a force acting over a period of time, represented by the shaded area.

• The rate of change of momentum of an object.

• The distance traveled by an object in a given time.

• The energy transferred to an object by a force.

What is Momentum?

• The force exerted by an object in motion.

• The product of an object's mass and its velocity, representing the quantity of motion of a moving body.

• The energy possessed by a body due to its position or motion.

• The rate at which an object changes its velocity.

What is Torque?

• A measure of the twisting force that causes an object to rotate about an axis, the rotational equivalent of force.

• The linear force applied to an object in motion.

• The speed at which an object rotates around a fixed point.

• The distance traveled by an object in a given time.

Frame of Reference

• A coordinate system or set of axes used to measure the position, orientation, and motion of objects.

• A method for calculating the speed of light in a vacuum.

• A technique for analyzing the forces acting on an object.

• A framework for understanding the laws of thermodynamics.

What does the Impulse-Momentum Theorem state?

• The impulse acting on an object is equal to the object's change in momentum.

• Momentum is always conserved in a closed system.

• Impulse is the product of mass and velocity.

• The change in momentum is independent of the force applied.

What is Angular Impulse?

• The product of the average torque on a rotating object and the time interval over which the torque acts.

• The force applied to an object in a straight line.

• The change in velocity of an object due to an external force.

• The rotational equivalent of linear momentum.

What is Angular Momentum?

• The product of an object's mass and velocity.

• The rotational equivalent of linear momentum, defined as the product of an object's moment of inertia and angular velocity.

• The force applied to an object to change its motion.

• The energy possessed by an object due to its position.

What is the Moment of Inertia?

• A measure of an object's resistance to linear motion.

• A quantity measuring an object's resistance to angular acceleration, dependent on its mass and mass distribution from the axis.

• The speed at which an object rotates around an axis.

• A force that causes an object to rotate.

What is a Binary Star System?

• A system of two stars that orbit each other around their common center of mass due to their mutual gravity.

• A single star that has a planet orbiting around it.

• A group of stars that are located in the same galaxy but do not interact with each other.

• A system of stars that are all part of a larger constellation.

What does the Angular Impulse-Angular Momentum Theorem state?

• A principle stating that the angular impulse on an object equals the object's change in linear momentum.

• A principle stating that the angular impulse on an object equals the object's change in angular momentum.

• A principle stating that the angular impulse on an object equals the object's mass times its velocity.

• A principle stating that the angular impulse on an object equals the object's change in kinetic energy.
