Midterm Exam Review: Velocity, Acceleration, Work, and Power

Flashcards covering key concepts of velocity, acceleration, work, and power for midterm exam review.

Velocity

The quantity that requires both magnitude and direction.

Acceleration

Measures the rate of change of an object's velocity.

Average Speed

Calculated as distance divided by time.

SI Units of Speed

Meters per second (m/s).

SI Unit of Force

Newton (N).

Work

The transfer of energy from one place to another, calculated as force multiplied by distance.

Power

The rate of energy transfer.

Formula for Work

W = F × d, where W is work, F is force, and d is distance.

Unit of Power

Watts (W), equivalent to joules per second (J/s).

Force Application

A force can be a push or a pull.

Newton's Second Law

Explains why 1 N is equal to 1 kg·m/s².

Average Acceleration

Change in velocity divided by the time over which the change occurs.
