TEKS Review

Which two measurements are needed in order to calculate the speed of an object in motion?

• distance and time

• time and mass

• force and distance

• volume and time

A block is pulled 1.8 m to the right in 5 s. What is the block's average speed to the nearest hundredth of a m/s? DO NOT FORGET TO INCLUDE UNITS!

A student throws a football three times. Another student records the distance, the amount of time the ball travels and the average speed in the table above. How many seconds did it take for the ball to travel 40 m during the third throw?

• 0.5 s

• 1.0 s

• 1.5 s

• 2.0 s

Students pulled the same mass up an inclined plane that was 20 cm, 30 cm, and 40 cm long. Each time, they used a spring scale to measure the force needed to pull the mass up the inclined plane. What did they conclude?

• Less force was needed on the 20 cm plane

• More force was needed on the 40 cm inclined plane.

• The least amount of force was needed on the 40 cm inclined plane.

• The least amount of force was needed on the 30 cm inclined plane.
