FLASHCARD QUESTION
Front
What is the formula to calculate the distance fallen during free fall?
Back
The formula is d = 0.5 * g * t², where d is the distance, g is the acceleration due to gravity, and t is the time in seconds.

FLASHCARD QUESTION
Front
What is the difference between mass and weight?
Back
Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in newtons (N). Weight can be calculated as W = m * g.

FLASHCARD QUESTION
Front
How does free fall differ on Mars compared to Earth?
Back
Free fall on Mars is affected by its lower gravitational acceleration (approximately 3.71 m/s²) compared to Earth's 9.81 m/s², resulting in a slower fall.

FLASHCARD QUESTION
Front
What is terminal velocity?
Back
Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is falling.

FLASHCARD QUESTION
Front
What does a horizontal line on a velocity-time graph indicate?
Back
A horizontal line indicates constant velocity, meaning the object is moving at a steady speed without acceleration.
