Speed and Velocity

Front

What is the formula to calculate speed?

Back

S = d/t

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What unit is commonly used to measure speed in the United States?

Back

Miles per hour (mph)

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

If a car travels 60 miles in 1 hour, what is its speed?

Back

60 mph

Front

What is the distance traveled if a person walks 3 km north and then 4 km east?

Back

7 km (using the Pythagorean theorem, the distance is the hypotenuse of a right triangle).

Front

What is the formula for calculating acceleration?

Back

a = (final velocity - initial velocity) / time

Front

What does a speedometer measure?

Back

A speedometer measures the speed of a vehicle.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the ending point, including direction.

Front

What is a vector quantity?

Back

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