- A racecar driver steps on the gas, and his racecar travels 20 meters in 2 seconds starting from rest. The acceleration of the racecar is
- What is the proper abbreviation for ‘kilohertz?’
- Instantaneous speed and average speed are equal
- What is the proper abbreviation for ‘grams?’
- A ball is dropped from a rooftop of a building and falls for two seconds. The acceleration of gravity is 9.8 m/s2. The ball is referred to at the two-second time.
- A racecar driver steps on the gas, changing his speed from 10 m/s to 30 m/s in 4 seconds. The acceleration of the racecar is
- A body at the end of a spring oscillates up and down ten times in five seconds. The period of oscillation is
- The slope of a distance vs. time graph is the
- The acceleration of a ball as it rolls down a ramp is 4 m/s2. The ball is referred to 2 s after it starts to roll.
- The figure shows a distance vs. time graph of an object with three distinct regions, I, II, and III. The object’s velocity is negative in region(s)
- The figure shows a distance vs. time graph of an object with three distinct regions, I, II, and III.

- A racecar driver steps on the gas, changing his speed from 10 m/s to 30 m/s in 4 seconds. The acceleration of the racecar is 10 m/s2.
- Twenty milliseconds is 0.020 s.
- A body at the end of a spring oscillates up and down ten times in five seconds. The period of oscillation is 2 s.
- The figure shows the distance versus time graph of an object. The acceleration of the moving object is a non-zero constant.
- The slope of a distance vs. time graph is the acceleration.
- The acceleration of a ball as it rolls down a ramp is 4 m/s2. The ball is referred to 2 s after it starts to roll.
- The figure shows a distance vs. time graph of an object with three distinct regions, I, II, and III. The object is never at rest.
- A fast-moving body must have a larger acceleration than a slow-moving body.
- If an object’s speed is constant, its velocity must also be constant.
- The proper abbreviation for ‘kilohertz’ is ‘kHz.’
- Select the closest matching pairs possible. 3 pts for each response.
