1024 can be written in scientific notation as______________?
Correct answer: A. 1.024 x 10^3
- A. 1.024 x 10^3
- B. 2 Raised to power 10
- C. 0.000976
- D. 1/0.00097
Explanation
Scientific notation requires one nonzero digit before the decimal point, so 1024 = 1.024 × 10^3. Although 1024 = 2^10 is also mathematically true, it is not scientific notation, which is why students may choose b.

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
