Quantification: Velocity and Acceleration

Front

What is velocity?

Back

Velocity is the rate of change of an object's position with respect to time, including direction. It is a vector quantity.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating average velocity?

Back

Average velocity = (Final position - Initial position) / (Time interval).

Front

What is the standard unit of acceleration in the International System of Units (SI)?

Back

The standard unit of acceleration is meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

How do you calculate the total displacement of an object?

Back

Total displacement is calculated as the final position minus the initial position, taking direction into account.

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

If an object moves from 0 m to 10 m in 5 seconds, what is its average velocity?

Back

Average velocity = (10 m - 0 m) / 5 s = 2 m/s.

Front

What is the effect of gravity on falling objects?

Back

All objects fall at an acceleration of approximately 9.8 m/s² due to gravity, regardless of their mass.

Front

How can you determine acceleration from a velocity-time graph?

Back

Acceleration is the slope of the velocity-time graph. A steeper slope indicates greater acceleration.
