Front

What is the formula to calculate speed?

Back

S = d/t

Front

What is the unit to MEASURE force?

Back

Newton

Front

What does a graph showing a straight line represent?

Back

Constant Speed

Front

What is Newton's 1st Law of Motion?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

a = (final velocity - initial velocity) / time

Front

What is the unit of measurement for acceleration?

Back

Meters per second squared (m/s²)

Front

What does a downward slope on a distance-time graph indicate?

Back

The object is returning to the starting point.
