Physics Unit 1 Flashcard Review

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

Define displacement in physics.

Back

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

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered, while displacement is a vector quantity that refers to the change in position.

Front

What is a vector quantity? Give an example.

Back

A vector quantity has both magnitude and direction. Example: Velocity.

Front

What is a scalar quantity? Give an example.

Back

A scalar quantity has only magnitude and no direction. Example: Speed.

Front

How do you calculate the time taken if you know distance and speed?

Back

Time = Distance / Speed

Front

What is the unit of speed in the SI system?

Back

Meters per second (m/s)

Front

If a ball is thrown straight up and falls back to the same spot, what is its total displacement?

Back

Zero.

Front

What is the relationship between speed, distance, and time?

Back

Speed is the ratio of distance traveled to the time taken.

Front

What is the significance of direction in vector quantities?

Back

Direction is essential in vector quantities as it determines the vector's orientation in space.
