Week 15 Flashcard 7th

Front

What is velocity?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

Which is faster: walking, skating, or biking?

Back

Biking is faster than both walking and skating.

Front

How do you calculate time when distance and speed are known?

Back

Time = Distance ÷ Speed.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, without regard to 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

If a bus travels at 50 km/h, how long will it take to travel 125 km?

Back

It will take 2.5 hours.

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude (e.g., speed, distance).

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction (e.g., velocity, displacement).
