Linear Motion Review MCHS

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the difference between instantaneous speed and average speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time, while average speed is the total distance traveled divided by the total time taken.

Front

What is a frame of reference?

Back

A frame of reference is a set of coordinates or a perspective from which motion is observed and measured.

Front

What happens to the acceleration of an object moving at constant velocity?

Back

The acceleration of an object moving at constant velocity is zero.

Front

What direction is the acceleration of a ball tossed upward?

Back

The acceleration of a ball tossed upward is always directed downward due to gravity.

Front

What is the most common frame of reference used in physics?

Back

The most common frame of reference used in physics is Earth.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is uniform motion?

Back

Uniform motion is when an object moves at a constant speed in a straight line.
