Back

The resultant is the sum of the vectors.

Front

When measuring distance, how does the number change as the units get bigger?

Back

Front

Define vector in physics.

Back

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

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.

Front

What is the formula for calculating the magnitude of a resultant vector?

Back

Magnitude = √(x² + y²) where x and y are the components of the vector.

Front

What is the unit of measurement for force in the International System of Units (SI)?

Back

Newton (N).

Front

What does the term 'displacement' mean in physics?

Back

Displacement is the shortest distance from the initial to the final position, along with the direction.
