Unit 5 Lesson 5+6

What is motion?

• A change in position over time

• The speed of an object

• The distance an object has traveled

• The rate of speeding up, slowing down, or changing direction

What does velocity include?

• Position and speed

• Acceleration and time

• Distance and time

• Speed and direction

What is acceleration?

• The rate of speeding up, slowing down, or changing direction

• The distance an object has traveled

• A change in position over time

• The speed of an object

What is the equation for speed?

• Speed = distance/time

• Speed = time/distance

• Speed = distance x time

• Speed = time x distance

Which of the following is an example of velocity?

• 10 m/s

• 300 km/hr

• 5 m/s north

• 5 m/s^2

What does acceleration involve?

• Acceleration and time

• Position and speed

• Speed and direction

• Distance and time

A high-speed train has a speed of 300 km/hr. How far will it travel in 5 hours?

• 2500 km

• 1200 km

• 600 km

• 1500 km

What is the definition of speed?

• The rate of speeding up, slowing down, or changing direction

• The speed of an object

• The distance an object has traveled

• How fast or slow an object is changing position (rate)

What is the equation for acceleration?

• Acceleration = velocity/change in time

• Acceleration = change in time/change in velocity

• Acceleration = time/change in velocity

• Acceleration = change in velocity/change in time

After 0.5 seconds, the blue car had traveled 2 meters across the floor. What is the average speed of the blue car in m/sec?

• 0.25 m/sec

• 0.25 cm/sec

• 2.5 m/sec

• 4 m/sec
