Vector or Scalar

Front

What is the definition of a vector?

Back

A vector is a quantity that has both direction and magnitude.

Front

What is the definition of a scalar?

Back

A scalar is a quantity that has only magnitude and no direction.

Front

What is displacement?

Back

Displacement is a vector quantity that refers to the change in position of an object.

Front

What is the resultant of two or more vectors?

Back

The resultant is the vector sum of two or more vectors.

Front

What is magnitude in the context of vectors?

Back

Magnitude refers to the greatness of size, strength, or importance of a vector.

Front

Which of the following is a vector: speed or velocity?

Back

Velocity is a vector because it has both direction and magnitude.

Front

What is an example of a scalar quantity?

Back

An example of a scalar quantity is temperature.

Front

How do you represent a vector graphically?

Back

A vector is represented graphically by an arrow, where the length indicates magnitude and the direction of the arrow indicates direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered, while displacement is a vector that refers to the change in position.

Front

What is the formula for calculating the resultant of two vectors at right angles?

Back

The resultant can be calculated using the Pythagorean theorem: R = √(A² + B²), where A and B are the magnitudes of the two vectors.
