• 9.8 m/s²

• 10 m/s²

• 8.5 m/s²

• 9.8 km/s²

Which of the following is an example of balanced forces?

• A car accelerating on the highway.

• A book resting on a table.

• A plane taking off.

• A rolling ball coming to a stop.

Newton's First Law of Motion is also known as the law of:

• Inertia

• Acceleration

• Action and reaction

• Conservation

What two variables influence an object's terminal velocity?

Compare velocity over time and position over time graphs. How are they different?

• Velocity-time graphs show speed; position-time graphs show distance.

• Velocity-time graphs show acceleration; position-time graphs show velocity.

• Velocity-time graphs show speed; position-time graphs show time.

• Velocity-time graphs show velocity; position-time graphs show position.
