Scalar And Vector Quantity

Front

What is a scalar quantity?

Back

A physical quantity that has magnitude but no direction.

Front

What is a vector quantity?

Back

A physical quantity that has both magnitude and direction.

Front

What is the x-component of a vector?

Back

The projection of the vector along the x-axis, calculated as the vector's magnitude multiplied by the cosine of the angle with respect to the x-axis.

Front

What happens when you multiply a vector by a scalar?

Back

The result is a vector that has the same direction as the original vector but a different magnitude.

Front

What happens when you divide a vector by a scalar?

Back

The result is a vector that has the same direction as the original vector but a different magnitude.

Front

What is the resultant of two vectors?

Back

The vector that represents the combined effect of the two vectors.

Front

How do you find the resultant of two vectors acting in the same direction?

Back

Add their magnitudes together.

Front

How do you find the resultant of two vectors acting in opposite directions?

Back

Subtract the smaller magnitude from the larger magnitude.

Front

What is the significance of direction in vector quantities?

Back

Direction determines how the vector interacts with other vectors and affects the resultant.

Front

What is parabolic motion?

Back

The motion of an object that follows a curved path under the influence of gravity, such as a stone thrown into a lake.
