What is the formula for calculating distance in uniform motion?
Distance = Speed x Time
True or False: In motion with constant acceleration, the velocity of an object changes at a constant rate.
True
Fill in the blank: The formula for calculating final velocity (v) is ________.
v = u + at
What does ‘u’ represent in the formula v = u + at?
Initial velocity
What is the formula for calculating acceleration?
Acceleration (a) = (Final velocity - Initial velocity) / Time
True or False: The area under a velocity-time graph represents distance traveled.
True
What is the formula for calculating distance when acceleration is constant?
Distance = ut + (1/2)at^2
Fill in the blank: The formula to calculate the time taken when distance and velocity are known is ________.
Time = Distance / Speed
What is the unit of acceleration in the SI system?
Meters per second squared (m/s²)
What is the formula for calculating final position (s) in uniformly accelerated motion?
s = ut + (1/2)at²
True or False: If an object is moving in a straight line with constant speed, its acceleration is zero.
True
What does ‘a’ represent in the equation s = ut + (1/2)at²?
Acceleration
Multiple Choice: Which of the following equations is used to find the final velocity without time? A) v² = u² + 2as B) v = u + at C) s = ut + (1/2)at²

What is the formula for average speed?
Average Speed = Total Distance / Total Time
Fill in the blank: The unit of distance in the SI system is ________.
Meters (m)
True or False: A body in motion will continue to move with constant velocity unless acted upon by a net external force.
True
What is the relationship between distance, speed, and time?
Distance = Speed x Time
What is the formula used to calculate the displacement of an object?
Displacement = Final Position - Initial Position
Multiple Choice: Which of the following is true about constant velocity? A) It means no acceleration B) It means changing direction C) It means speed is increasing
A) It means no acceleration
What is the formula for calculating the change in velocity?
Change in velocity = Final velocity - Initial velocity
Fill in the blank: The term for speed with a direction is ________.
Velocity
What does ‘s’ represent in the equation s = ut + (1/2)at²?
Displacement
True or False: The initial velocity can be negative if the object is moving in the opposite direction.
True
What is the formula for calculating the distance fallen by an object in free fall after time t?
Distance = (1/2)gt²
