Test 1.1-1.8 Review

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

What does a positive acceleration indicate?

Back

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

Front

What does a negative acceleration (deceleration) indicate?

Back

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

Front

What is velocity?

Back

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

Front

What is the difference between speed and velocity?

Back

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

Front

What does a constant speed mean in terms of acceleration?

Back

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

Front

What does the slope of a Velocity vs Time graph represent?

Back

The slope of a Velocity vs Time graph represents acceleration.

Front

What is the significance of a horizontal line on a Velocity vs Time graph?

Back

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