What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is a scalar quantity and does not have a direction.

Front

How is velocity different from speed?

Back

Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down, also known as deceleration.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force 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 -9.8 m/s², often rounded to -10 m/s² for simplicity in calculations.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity and is conserved in isolated systems.

Front

How do you calculate momentum?

Back

Momentum (p) = Mass (m) x Velocity (v).

Front

What is displacement?

Back

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