Review: Mod. 1The Kinematic Equations

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the unit of acceleration?

Back

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

Front

When is an object said to be in uniform motion?

Back

An object is in uniform motion when it covers equal distances in equal intervals of time.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line on a distance-time graph indicates that the object is not moving.

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 formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What is the kinematic equation for final velocity?

Back

Final velocity (v) = Initial velocity (u) + Acceleration (a) × Time (t).

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.

Front

What is the kinematic equation relating distance, initial velocity, time, and acceleration?

Back

Distance (s) = Initial velocity (u) × Time (t) + 0.5 × Acceleration (a) × Time² (t²).

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the total distance traveled by the object.
