ACCELERATIONTHE CHANGE IN VELOCITY

ACCELERATION

•Acceleration is the rate of change in an object’s velocity.

•The unit is m/s²

•Velocity / time = (m/s)/s = m/s²

•Average acceleration is found by using the

following equation:

•

ACCELERATION: CAR EXAMPLE

The 2015 Ford Mustang Shelby GT500 has a

0-60 mph in 3.5s

ACCELERATION: CAR EXAMPLE

0-60 mph in 3.5s

With this data we can calculate the average acceleration.

MARIO AND PHYSICS

Mario throws a fireball straight up with an initial velocity of 29.4 m/s ~ 66 mph.

It reach its peak at 3.0 s, and then lands back in Mario’s hand at 6.0 s. Find the average acceleration.
