Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes displacement?
The total distance covered by an object.
The change in an object's position in a specific direction.
The rate at which an object changes its speed.
The force acting on an object.
2. An object moving at a constant velocity has:
Zero displacement.
Constant acceleration.
Zero acceleration.
Increasing speed.
1. The SI unit for velocity is .
2. Acceleration is the rate of change of .
3. A scalar quantity has magnitude only, while a vector quantity has both magnitude and .
1. A car travels 100 km north and then 50 km south. What is the car's total distance traveled and its displacement?
2. Explain the difference between speed and velocity.
1. An object can have zero velocity but non-zero acceleration.
True
False
2. The slope of a position-time graph represents acceleration.
True
False
1. A ball is thrown vertically upward with an initial velocity of 20 m/s from the ground. Calculate:
a) The maximum height reached by the ball.
b) The time it takes for the ball to return to the ground.
