Motion: Velocity, Acceleration & Momentum

Front

What is the equation for velocity?

Back

V = displacement ÷ time

Front

What does a graph showing a downward slope indicate?

Back

Negative acceleration

Front

What is the definition of momentum?

Back

Mass in motion

Front

What does a horizontal line on a distance-time graph represent?

Back

Constant velocity

Front

How do you calculate acceleration?

Back

Acceleration = (final velocity - initial velocity) ÷ time

Front

What is the unit of momentum?

Back

kg·m/s

Front

What is the difference between speed and velocity?

Back

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

Front

What does a positive slope on a velocity-time graph indicate?

Back

Acceleration

Front

If an object is at rest, what is its velocity?

Back

0 m/s

Front

What is the formula for calculating momentum?

Back

Momentum = mass × velocity
