Speed, Velocity & Acceleration

Front

Speed = _______________

Back

Distance / time

Front

Avery likes to walk 30 feet in 10 seconds. What is her speed?

Back

3 feet/sec

Front

If these teams are pulling with the same amount of force what will happen?

Back

They will not move at all.

Front

This occurs when an object speeds up, slows down, or changes direction.

Back

Acceleration

Front

Changes in our speed, direction or both are called _________.

Back

acceleration

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / time

Front

What is the difference between speed and velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time.

Front

If a car increases its speed from 20 m/s to 50 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / time = (50 m/s - 20 m/s) / 5 s = 6 m/s²

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.
