Midterm Review #2 Kinematics

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is uniform velocity?

Back

Uniform velocity means that an object covers equal distances in equal intervals of time, regardless of the length of the time intervals.

Front

What is the formula for calculating velocity?

Back

Velocity = Distance / Time.

Front

If a body is moving with uniform velocity, what is its acceleration?

Back

0 (zero), because there is no change in velocity.

Front

What does v_i represent in kinematics?

Back

v_i represents initial velocity.

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

How do you calculate the time taken if you know acceleration and change in velocity?

Back

Time = (Final Velocity - Initial Velocity) / Acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a plane travels 3000 miles in 5 hours, what is its velocity?

Back

600 mph west.
