Physics Midterm Review

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate displacement in projectile motion?

Back

Displacement in projectile motion can be calculated using the horizontal velocity and the time of flight. Displacement = horizontal velocity × time.

Front

What does the slope of a position vs. time graph represent?

Back

The slope of a position vs. time graph represents the average velocity of the object.

Front

What is the significance of a horizontal line on a velocity vs. time graph?

Back

A horizontal line on a velocity vs. time graph indicates that the object is moving at a constant velocity.

Front

What does a negative average velocity indicate?

Back

A negative average velocity indicates that the object is moving in the opposite direction to the defined positive direction.

Front

How do you determine if an object is at rest using a graph?

Back

An object is at rest if the position vs. time graph is a horizontal line, indicating no change in position over time.

Front

What is the formula for calculating average velocity?

Back

Average velocity = (final position - initial position) / (final time - initial time).

Front

What is the effect of gravity on a projectile?

Back

Gravity causes a projectile to accelerate downwards, affecting its vertical motion while it moves horizontally.

Front

How can you find the time of flight for a projectile?

Back

The time of flight can be found using the formula: time = √(2h/g), where h is the height and g is the acceleration due to gravity.

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.
