What is the equation to calculate speed?
A) Speed = Distance × Time
B) Speed = Mass × Acceleration
C) Speed = Energy ÷ Time
D) Speed = Force × Distance
Correct Answer:
A) Speed = Distance × Time
Explanation:
The formula to calculate speed is Speed = Distance ÷ Time. This equation expresses that speed is the rate at which an object covers a certain distance in a specific amount of time. It’s a fundamental formula in physics and is commonly used to measure how fast something is moving. Option B is the formula for calculating force (Newton’s second law), option C does not represent a formula for speed, and option D represents the equation for calculating work (force × distance).
