kinematics and dynamics

What defines scalar quantities?

Scalar quantities are defined by magnitude only, represented by a single number.

Give examples of scalar quantities.

Examples include mass, distance, speed, and time.

What characterizes vector quantities?

Vector quantities are characterized by both magnitude and direction.

Provide examples of vector quantities.

Examples include velocity, acceleration, and displacement.

How is distance measured?

Distance is a scalar quantity measured by adding all individual paths taken by an object.

What is displacement?

Displacement is a vector quantity measuring the straight-line distance from the starting point to the ending point, including direction.

What is the Pythagorean theorem used for in measuring displacement?

The Pythagorean theorem is used to find the length of the displacement, calculating the hypotenuse with √(a² + b²).

What does SOHCAHTOA refer to in relation to displacement?

SOHCAHTOA is used for finding bearings in displacement calculations.

Why is it important to add squares in Pythagorean calculations?

It is important to add squares (²) to properly apply the Pythagorean theorem for measuring lengths in displacement.
