What is the first step in calculating the acceleration of an object from a velocity versus time graph?

• Determine the object's mass.

• Find the area under the graph.

• Calculate the slope of the graph.

• Choose two different points on the graph.

What is the initial velocity of the object at time T = 0 seconds?

• 10 meters per second

• 20 meters per second

• 5 meters per second

• 0 meters per second

How long does it take for the object's velocity to change from 0 to 20 meters per second?

• 5 seconds

• 10 seconds

• 15 seconds

• 20 seconds

What is the formula for acceleration?

• Change in time divided by change in velocity

• Change in velocity divided by change in time

• Time divided by velocity

• Velocity multiplied by time
