Kinematics Semester Review

Front

What is acceleration?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for calculating speed?

Back

Speed (S) is calculated using the formula: S = D/T, where D is distance and T is time.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position, including direction.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s).

Front

What does it mean when an object is in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time, maintaining a constant speed.

Front

What is the significance of negative acceleration?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

How does changing direction affect acceleration?

Back

Changing direction while maintaining speed results in acceleration because acceleration is a vector quantity that depends on both speed and direction.

Front

What is the formula for calculating distance when speed and time are known?

Back

Distance (D) can be calculated using the formula: D = S × T, where S is speed and T is time.

Front

What is the relationship between speed, distance, and time?

Back

The relationship is defined by the formula: Speed = Distance / Time.
