Vectors

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity or force.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as speed or mass.

Front

List three examples of vector quantities.

Back

Velocity, acceleration, force.

Front

List three examples of scalar quantities.

Back

Speed, mass, time.

Front

What is the resultant displacement?

Back

The resultant displacement is the overall change in position of an object, taking into account both magnitude and direction.

Front

How do you calculate the resultant displacement of two vectors?

Back

To calculate the resultant displacement, use vector addition, which may involve breaking vectors into components and then summing those components.

Front

What is the y-component of a vector?

Back

The y-component of a vector is the projection of the vector in the vertical direction, often calculated using trigonometric functions.

Front

What is the significance of direction in vector quantities?

Back

Direction is crucial in vector quantities as it determines the vector's effect in a physical context, such as the direction of motion or force.

Front

If a car travels 90 meters north and then 40 meters south, what is its resultant displacement?

Back

50 meters, North.

Front

What does it mean for a vector to be 'resolved'?

Back

Resolving a vector means breaking it down into its components, typically along the x and y axes.
