|
Momentum...
Scalar or Vector? |
Momentum is a VECTOR quantity. The direction of a momentum vector is in the same direction as the direction of the moving object (same as the object's velocity).
|
|
|
Speed...
Scalar or Vector? |
Speed is a SCALAR quantity. Speed is a quantity that measures the rate of change of an object's distance and does not include a direction.
|
|
|
Mass...
Scalar or Vector? |
Mass is a SCALAR quantity. Mass is a measure of how much matter an object is made of.
|
|
|
Friction...
Scalar or Vector? |
Friction is a force, therefore it is a VECTOR quantity. All forces are vector quantities. A friction force tends to oppose an object's motion.
|
|
|
Work...
Scalar or Vector? |
Work is a SCALAR quantity. Although Work is a product of two vectors (force and displacement), it is a quantity that does not include a direction.
|
|
|
Displacement...
Scalar or Vector? |
Displacement is a VECTOR quantity. Displacement measures how far an object is from its original position and in what direction it has moved.
|
|
|
Impulse...
Scalar or Vector? |
Impulse is a VECTOR quantity. Impulse represents a change in an object's momentum and is a result of a force. The direction of the force will represent the direction of an object's impulse.
|
|
|
Inertia...
Scalar or Vector? |
Inertia is a SCALAR quantity. Inertia represents an object's resistance to a change in its current state of motion. Inertia is related to an object's mass, which is a scalar quantity.
|
|
|
Kinetic Energy...
Scalar or Vector? |
Kinetic Energy is a SCALAR quantity. Kinetic Energy is a form of energy and all forms of energy are scalar.
|
|
|
Acceleration...
Scalar or Vector? |
Acceleration is a VECTOR quantity. Acceleration represents the rate of change of an object's velocity.
