1st semester review

Front

What does a graph representing zero acceleration look like?

Back

A horizontal line indicating constant velocity.

Front

Which runner got a head start in a race?

Back

The runner whose line starts before the others, indicating they began running earlier.

Front

Convert 674.3 mm to scientific notation.

Back

6.743 × 10² mm.

Front

How do you calculate final velocity with constant acceleration?

Back

Final velocity = initial velocity + (acceleration × time).

Front

What is the final velocity of a toy car with an initial velocity of 5.0 m/s and a constant acceleration of 2.0 m/s² after 6.0 seconds?

Back

17 m/s.

Front

Convert 7896 millimeters to meters.

Back

7.896 m.

Front

What is the formula for acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

Define scientific notation.

Back

A method of expressing numbers as a product of a coefficient and a power of ten.

Front

What does a slope of a distance-time graph represent?

Back

The speed or velocity of the object.

Front

What is the difference between speed and velocity?

Back

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