Physical Science Midterm Review 24-25

Front

What does a negative velocity indicate?

Back

An object is moving in the opposite direction to the positive reference direction.

Front

What does a velocity of 0 m/s mean in terms of motion?

Back

The object is not moving.

Front

What does a position vs. time graph show when the line is straight and sloped?

Back

The object is moving with constant velocity.

Front

What does a position vs. time graph show when the line is curved?

Back

The object is moving with changing velocity.

Front

What does a horizontal line on a position vs. time graph indicate?

Back

The object is not moving.

Front

How can you determine if an object is speeding up or slowing down from a velocity vs. time graph?

Back

If the velocity is increasing, the object is speeding up; if the velocity is decreasing, the object is slowing down.

Front

What is the significance of the slope in a position vs. time graph?

Back

The slope represents the velocity of the object.

Front

What does a negative slope in a position vs. time graph indicate?

Back

The object is moving in the negative 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 it mean if an object has a constant velocity?

Back

The object is moving at the same speed and in the same direction.
