Phy8_Velocity and acceleration time graphs review

Front

What is velocity?

Back

Velocity is the rate of change of displacement with respect to time, and it includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity with respect to time.

Front

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

Back

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

Front

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

Back

A positive slope indicates that the object is accelerating in the positive direction.

Front

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

Back

A negative slope indicates that the object is accelerating in the negative direction.

Front

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

Back

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

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 significance of the area under the curve in a velocity-time graph?

Back

The area under the curve represents the total distance traveled by the object.

Front

What does it mean when the velocity is zero?

Back

When the velocity is zero, the object is at rest.

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration means an increase in velocity, while negative acceleration (deceleration) means a decrease in velocity.
