Physics Flashcard

Front

What does a negative slope indicate on a graph?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What does velocity represent in physics?

Back

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

Front

What is acceleration?

Back

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

Front

Which of the following does not describe an acceleration: Pedaling faster, turning a corner, coasting, hitting the brakes?

Back

Coasting does not describe an acceleration.

Front

How is a change in direction represented on a position-time graph?

Back

A change in direction is represented by a line that initially moves upwards and then turns downward.

Front

What is the unit of electric current?

Back

The unit of electric current is the ampere (amp).

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does a flat, horizontal line on a position-time graph indicate?

Back

A flat, horizontal line indicates that the object is at rest.

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 is the significance of the y-axis in a position-time graph?

Back

The y-axis represents the position of the object.
