Acceleration and Speed Graphs

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

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 the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What does a flat line on a speed graph indicate?

Back

A flat line indicates that the object is stationary (not moving).

Front

What does a steep slope on a speed graph indicate?

Back

A steep slope indicates that the object is moving at a high speed.

Front

What does a downward slope on a speed graph indicate?

Back

A downward slope indicates that the object is slowing down.

Front

What is the SI unit for speed?

Back

The SI unit for speed is meters per second (m/s).

Front

What does a curve on an acceleration graph indicate?

Back

A curve indicates that the acceleration is changing over time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
