Speed and Acceleration Problems

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for acceleration?

Back

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

Front

What is the unit of distance?

Back

Common units of distance include meters (m), kilometers (km), feet, and miles.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line with a positive slope on a distance-time graph.

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line indicates constant speed; the object is moving at the same speed over time.

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 car travels 60 meters in 3 seconds, what is its speed?

Back

Speed = 60 m / 3 s = 20 m/s.

Front

What does negative acceleration indicate?

Back

Negative acceleration (deceleration) indicates that an object is slowing down.
