CP Ch02.1 Acceleration

What did Galileo experiment with to develop the concept of acceleration?

• Magnetism

• Electricity

• Inclined planes

• Gravity

In Galileo's Experiment, what changed as he changed the inclined plane?

• Velocity

• Distance

• Gravity

Which of these is NOT an example of acceleration or deceleration?

• Slowing Down

• Stepping on a gas pedal

• Driving at Constant Speed

• When a Car makes a turn

What units are used to measure acceleration?

• Meters per second

• Kilometers per hour

• Feet per second squared

• Meters per second squared

What conditions need to change for acceleration to occur?

• Speed only

• Direction only

• Both speed and direction

• Neither speed nor direction

Which of these is NOT true about Free Fall?

• It is acceleration when wind resistance is not present

• The acceleration changes as an object is dropped at Free Fall

• Acceleration is always 9.8 or 10 m/s²

• Dropping an object will have the same acceleration on Earth

What is the acceleration rate of freely falling objects?

• 5 m/s

• 9.8 m/s²

• 15 m/s

• 20 m/s
