True
True or false: Distance and displacement are always the same value.
False
True or false: Tycho Brahe made accurate observations of the planets' positions over time.
True
True or false: Galileo concluded that all objects fall at the same rate in a vacuum.
True
True or false: Displacement includes both the distance and direction involved in a change in position.
True
True or false: Distance is always positive, while displacement may be positive or negative.
True
True or false: Scalar quantities have both magnitude and direction.
False
True or false: Vector quantities consist of magnitude (size) only.
False
True or false: The Pythagorean theorem can be used to find the displacement value in two-dimensional motion.
True
True or false: The total distance traveled is always greater than or equal to the displacement.
True
True or false: Distance is a vector quantity.
False
True or false: Displacement is a measurable quantity that consists of magnitude (size) only.
False
What is a frame of reference?
A frame of reference is a coordinate system used to describe the motion of an object.
What is the difference between distance and displacement?
Distance is how far an object moves during a time interval, while displacement is a vector quantity that describes a change in position.
How is displacement calculated?
Displacement is calculated using the formula Δx = xf – xi, where Δx is the displacement (change in position), xf is the final position, and xi is the initial position.
What are scalars and vectors?
Scalars are measurable quantities that consist of magnitude (size) only, while vectors are measurable quantities with both magnitude and direction.
What is the nature of motion according to Aristotle?
According to Aristotle, objects naturally move towards their natural place based on their elements.
What is the study of motion called?
mechanics
What are the three laws of motion developed by Isaac Newton called?
Newton's laws of motion
What is the difference between classical mechanics and modern motion models?
Modern motion models are more complex, while classical mechanics is simpler but accurate enough for most objects
What is the basis for classical mechanics?
Isaac Newton's three laws of motion and law of universal gravitation
