Velocity and AccelerationQuiz - Solve & Score
Q1. Which of the following is a scalar quantity?
- A.Speed
- B.Velocity
- C.Displacement
- D.Acceleration
Answer: A. Speed
What is the textbook's take? Speed has only magnitude -> scalar. Does that line up with one of the options? Yes - Correct. And the rest? option B) 'Velocity' is incorrect: A vector; option C) 'Displacement' misses the point - A vector. Pick: A) Speed.
Q2. An object moves with constant speed along a curved path. Which quantity is definitely changing?
- A.its velocity, because direction is changing
- B.its speed
- C.nothing at all
- D.its mass
Answer: A. its velocity, because direction is changing
The idea this question leans on: Velocity is a vector; changing direction at constant speed still changes the velocity. That fits the listed correct option directly - Correct. Quickly on the wrong ones: option B) 'its speed' misses the point - Speed is stated to be constant; option C) 'nothing at all' doesn't hold - Direction changes on a curve, so velocity changes. Hence the answer is A) its velocity, because direction is changing.
Q3. Which situation describes a body with uniform velocity?
- A.moving in a straight line covering equal displacements in equal time intervals
- B.moving in a circle at constant speed
- C.speeding up along a straight road
- D.at rest at a fixed point
Answer: A. moving in a straight line covering equal displacements in equal time intervals
