Momentum and Impulse

What is the definition of Velocity?

• A scalar quantity indicating only the speed of an object.

• A vector quantity specifying the rate of change of an object's position, indicating both its speed and direction of motion.

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

• A measure of how fast an object is moving without regard to its direction.

What is mass?

• A measure of the amount of matter in an object and its inherent resistance to acceleration, also known as inertia.

• A measure of the volume of an object.

• The weight of an object in a gravitational field.

• The density of an object.

What is Angular Impulse?

• The change in an object's linear momentum.

• The change in an object's angular momentum, calculated as the product of the average torque and its duration.

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

• The speed of an object in circular motion.

What is Angular Momentum?

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

• A measure of the force applied to an object in a circular path.

• The speed of an object moving in a straight line.

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

What is Angular Velocity?

• The rate at which an object rotates or revolves about an axis, specifying both rotational speed and direction.

• The speed of an object moving in a straight line.

• The distance traveled by an object in a circular path.

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

What is a Frame of Reference?

• A method of measuring temperature

• A coordinate system or set of axes used to measure and describe the motion and properties of objects.

• A type of physical frame used in construction

• A psychological perspective on human behavior

What is Total Momentum?

• The total energy of a system of objects.

• The vector sum of the individual momenta of all the objects that are contained within a defined system.

• The measure of the speed of an object in a given direction.

• The total force acting on an object in motion.

Inertia

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The energy stored in an object due to its position.

• The speed of an object in motion.

What is Linear Momentum?

• The force applied to an object over time.

• The product of an object's mass and its velocity, representing the quantity of motion an object has in a straight line.

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

• The rate of change of an object's velocity.
