PS Unit Two Final Exam Review 2024

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

How do you calculate acceleration?

Back

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

Front

What is the formula for velocity?

Back

Velocity (v) is calculated using the formula: v = distance / time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.

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 does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph indicates that the object is at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope on a distance-time graph indicates a high speed.

Front

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

Back

The area under a velocity-time graph represents the distance traveled by the object.

Front

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

Back

If an object has a constant velocity, it means it is moving at the same speed and in the same direction.
