Physics Final Exam Conceptual Review

Front

What is the best hypothesis for studying the effects of caffeine on study duration?

Back

If I drink the highest caffeinated drink, then I will be able to study for the most amount of hours.

Front

What type of relationship is shown in a direct graph?

Back

A direct relationship indicates that as one variable increases, the other variable also increases.

Front

What is the acceleration of an object tossed straight up at 5m/s?

Back

-10 m/s² (due to gravity acting downwards).

Front

What is the base metric unit for measuring time?

Back

Seconds.

Front

What is the vertical acceleration of an object rolling off a table?

Back

-10 m/s² (due to gravity).

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) - Initial Velocity (u)) / Time (t).

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

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 is the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a).
