Question 15:
Suppose you take a trip that covers 180 km and takes 3 hours to make. Your average speed is
Question 16:
Suppose a car is moving in a straight line and steadily increases its speed. It moves from 35 km/h to 40 km/h the first second and from 40 km/h to 45 km/h the next second. What is the car's acceleration?
Question 17:
A ball is thrown straight up. At the top of its path its instantaneous speed is
Question 18:
The displacement of an object moving 330 km North for 2 hours and an additional 220 km North for 5 hours is
Question 19:
When something falls to the ground, it accelerates. This acceleration is called the acceleration due to gravity and is symbolized by the letter g. What is the value of g on Earth's surface?
Question 20:
A car accelerates at 2 m/s². Assuming the car starts from rest, how much time does it need to accelerate to a speed of 20 m/s?
Question 21:
If a freely falling object were somehow equipped with a speedometer, its speed reading would increase each second by
Question 22:
If a ball were equipped with a speedometer and allowed to fall freely on a planet where the acceleration due to gravity is 23 m/s², the reading on the speedometer would increase each second by
Question 23:
The rate at which distance is covered is called
Question 24:
Average speed is
- total distance traveled by the object divided by the elapsed time to cover that distance
Question 25:
Velocity is different from speed in that velocity is
Question 26:
A unit of velocity is
Question 27:
The rate at which velocity changes with time is called
