Physics Concepts in Motion

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time. The slope of the graph indicates acceleration.

Front

How do you calculate acceleration?

Back

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

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

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

Back

A horizontal line indicates that the object is moving at a constant velocity.

Front

What does a positive slope on a velocity-time graph indicate?

Back

A positive slope indicates that the object is accelerating.

Front

What does a negative slope on a velocity-time graph indicate?

Back

A negative slope indicates that the object is decelerating (slowing down).

Front

How can you determine the distance traveled from a velocity-time graph?

Back

The distance traveled can be determined by calculating the area under the velocity-time graph.

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 includes direction and is a vector quantity.

Front

What is the formula for calculating distance?

Back

Distance can be calculated using the formula: distance = speed × time.
