What is a scalar quantity?

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

• A scalar quantity is a physical quantity that has both magnitude and direction.

• A scalar quantity is a physical quantity that has magnitude but no direction.

• A scalar quantity is a physical quantity that has neither magnitude nor direction.

Give an example of a scalar quantity.

• Distance

• Velocity

• Force

• Temperature

What is a vector quantity?

• A vector quantity is a physical quantity that has neither magnitude nor direction.

• A vector quantity is a physical quantity that has only direction.

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

• A vector quantity is a physical quantity that has only magnitude.

Give an example of a vector quantity.

• velocity

• distance

• time

• speed

What is the formula to calculate the distance traveled during free fall?

• distance = g * t^2

• distance = (1/2) * g * t^2

• distance = g * t

• distance = (1/2) * g * t

What is the formula to calculate the final velocity during free fall?

• v = u + gt

• v = u - gt

• v = u + gt^2

• v = u * gt

What is the formula to calculate the time of flight during free fall?

• time = (height) / g

• time = (2 * height) / g

• time = sqrt((2 * height) / g)

• time = sqrt(height / g)

What is the formula to calculate the displacement during free fall?

• displacement = g * t^2

• displacement = g * t

• displacement = (1/2) * g * t

• displacement = (1/2) * g * t^2
