Question 1:
Which equation represents the relationship between displacement, initial velocity, time, and acceleration?
Explanation: The correct answer is C) v^2 = u^2 + 2ad. This equation is known as the second equation of motion. It relates the final velocity squared (v^2) to the initial velocity squared (u^2), twice the acceleration (2a), and the displacement (d).
Question 2:
Which equation can be used to calculate the final velocity of an object given the initial velocity, acceleration, and displacement?
Explanation: The correct answer is A) v = u + at. This equation is known as the first equation of motion. It allows us to calculate the final velocity (v) of an object based on the initial velocity (u), acceleration (a), and time (t).
Question 3:
What does the symbol "u" represent in the equations of motion?
Explanation: The correct answer is D) Initial velocity. In the equations of motion, the symbol "u" represents the initial velocity of an object. It is the velocity of the object at the beginning of the motion or at time zero.
Question 4:
Which equation can be used to calculate the displacement of an object given the initial velocity, final velocity, and time?
Explanation: The correct answer is C) d = (u + v)t / 2. This equation is known as the third equation of motion. It allows us to calculate the displacement (d) of an object based on the initial velocity (u), final velocity (v), and time (t).
Question 5:
Which equation can be used to calculate the acceleration of an object given the initial velocity, final velocity, and displacement?
Explanation: The correct answer is D) v^2 = u^2 + 2ad. This equation is known as the fourth equation of motion. It allows us to calculate the acceleration (a) of an object based on thevalues of the initial velocity (u), final velocity (v), and displacement (d). Rearranging the equation, we can isolate the acceleration term.
