2. Velocity
3. Scalar
4. Displacement

What type of physical quantity is speed?

1. Scalar
2. Displacement
3. Vector
4. Acceleration

What is the formula for calculating speed?

2. 3,000 m/s
3. 33,000 m/s
4. 300 m/s

What is the difference between speed and velocity?

1. Velocity gives direction to movement
2. Speed is a scalar quantity

Why is displacement used instead of distance in calculating velocity?

1. Displacement is always greater than distance
2. Displacement includes direction in its measurement

What does a negative value for velocity indicate?

1. Movement in the opposite direction of the reference point
2. A decrease in the object's size

What quantity is used to represent displacement in velocity calculations?

1. Letter 's'
2. Letter 'd'

How is velocity calculated?

1. Velocity = Distance x Time
2. Velocity = Displacement ÷ Time
