What is the formula to calculate the circumference of a circle?

Back

Circumference = 2 × π × radius

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the formula to calculate distance when acceleration is constant?

Back

Distance = Initial Velocity × Time + 0.5 × Acceleration × Time²

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the concept of centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is the initial velocity of an object?

Back

Initial velocity is the speed of an object at the start of a time interval.

Front

What is the significance of the peak height in projectile motion?

Back

At the peak height, the vertical velocity of the projectile is 0 m/s before it starts descending.

Front

How do you calculate the average speed of an object?

Back

Average Speed = Total Distance / Total Time.

Front

What is the formula for calculating the final velocity of an object?

Back

Final Velocity = Initial Velocity + (Acceleration × Time)

Front

What is the concept of displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.
