Physics - Semester 1 Review

Front

What does a slope of the position versus time graph indicate?

Back

Velocity

Front

What is the hiker’s velocity represented by line segment B (t= 2 - 10 seconds)?

Back

0.375 m/s

Front

What does velocity tell us in comparison to speed?

Back

Velocity tells us how fast an object is going and its direction of motion, while speed only tells us how fast the object is going.

Front

What does a slope of the velocity versus time graph indicate?

Back

Acceleration

Front

What are the units for acceleration?

Back

Front

Define position in physics.

Back

Position is the location of an object at a given time, relative to a reference point.

Front

What is the formula for calculating velocity?

Back

Velocity = \frac{\text{Displacement}}{\text{Time}}

Front

Explain the difference between scalar and vector quantities.

Back

Scalar quantities have magnitude only (e.g., speed), while vector quantities have both magnitude and direction (e.g., velocity).

Front

What is the formula for acceleration?

Back

Acceleration = \frac{\text{Change in Velocity}}{\text{Time}}

Front

What does a flat line on a position vs. time graph represent?

Back

A flat line indicates that the object is at rest (no change in position).
