Physics Ch 03 Accelerated Motion

Front

What is the acceleration of an object moving at constant velocity?

Back

The acceleration is zero.

Front

If a truck travels east while speeding up, in which direction is the acceleration?

Back

The acceleration is directed east.

Front

How can you determine which object has a higher rate of acceleration from a velocity vs time graph?

Back

The object with the steeper slope on the graph has a higher rate of acceleration.

Front

What is the speed of an apple after 1 second of free fall?

Back

The speed is approximately 9.8 m/s.

Front

How do you identify which object shows a larger rate of acceleration on a graph?

Back

The object represented by the line with the steeper slope shows a larger rate of acceleration.

Front

Define acceleration in physics.

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

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 is a vector quantity that includes both speed and direction.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only.
