Test 1.1-1.8 Review

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

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

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

A positive acceleration indicates that an object's velocity is increasing.

A negative acceleration indicates that an object's velocity is decreasing.

Velocity is the speed of an object in a specific direction.

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

When an object travels at a constant speed, its acceleration is zero.

The slope of a Velocity vs Time graph represents acceleration.

A horizontal line indicates that the object is moving at a constant velocity.
