Speed, Velocity, and Acceleration Notes Flashcard

Front

What is the SI unit of acceleration?

Back

Meter per second squared.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the difference between speed and velocity?

Back

Velocity is a vector quantity that includes direction, while speed is a scalar quantity that does not.

Front

What are the SI units for velocity?

Back

Meters per second.

Front

In what situation are a car’s velocity and acceleration in opposite directions?

Back

When the car is slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction.

Front

What is a vector quantity?

Back

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

Front

How does uniform acceleration differ from non-uniform acceleration?

Back

Uniform acceleration means the rate of change of velocity is constant, while non-uniform acceleration means the rate of change of velocity varies.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.
