What is 1D motion?

Back

1D motion refers to the movement of an object along a straight line, characterized by its position, velocity, and acceleration.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you calculate the distance traveled during uniform acceleration?

Back

Distance (s) = Initial Velocity (u) * Time (t) + 0.5 * Acceleration (a) * Time².

Front

What is the significance of the initial velocity in motion equations?

Back

The initial velocity is the starting speed of an object before any acceleration occurs, crucial for calculating distance and final velocity.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.
