Speed, Velocity, and Acceleration

Front

What is the definition of acceleration?

Back

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

Front

What are the three ways an object can accelerate?

Back

1. Increasing speed 2. Decreasing speed (deceleration) 3. Changing direction.

Front

How is speed defined in physics?

Back

Speed is the distance traveled per unit of time, regardless of direction.

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

What does a flat line on a distance vs. time graph indicate?

Back

A flat line indicates that the object is not moving.

Front

What does a steeper slope on a distance vs. time graph represent?

Back

A steeper slope indicates a higher speed.

Front

What does a negative slope on a distance vs. time graph indicate?

Back

A negative slope indicates that the object is moving back towards the starting position.

Front

What is the significance of the area under a velocity vs. time graph?

Back

The area under a velocity vs. time graph represents the displacement of the object.

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at a steady speed in a straight line without changing direction.

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration.
