Representing Motion in One Dimension

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include speed, mass, and temperature.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction. Examples include displacement, velocity, and force.

Front

What does the length of an arrow in a motion diagram represent?

Back

The length of the arrow indicates the distance from the origin.

Front

How do you convert 0.0005 to scientific notation?

Back

0.0005 can be written as 5 x 10^-4 in scientific notation.

Front

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

Back

Time = Distance / Velocity.

Front

If a bicyclist travels at a constant velocity of 4.0 m/s for 480 m, how long does it take?

Back

It takes 120 seconds.

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 refers to the speed of an object in a specific direction.

Front

What is displacement?

Back

Displacement is a vector quantity that refers to the change in position of an object, measured from the initial to the final position.

Front

What is the significance of scientific notation in physics?

Back

Scientific notation is used to express very large or very small numbers in a compact form, making calculations easier.

Front

What is acceleration?

Back

Acceleration is a vector quantity that represents the rate of change of velocity of an object over time.
