Review module 3: Periodic Table and Motion

Front

What is the formula to calculate time when distance and speed are known?

Back

Time = Distance / Speed

Front

What is the average speed if a car travels 300 km in 3 hours?

Back

Average Speed = 300 km / 3 hours = 100 km/hr

Front

What is a neutron?

Back

A subatomic particle with no electric charge found in the nucleus of an atom.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is a vector?

Back

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

Front

How do you calculate displacement?

Back

Displacement = Final Position - Initial Position.

Front

What is the unit of speed in the metric system?

Back

The unit of speed is meters per second (m/s) or kilometers per hour (km/hr).
