P1 - Measuments and Speed, velocity and accceleration

A drag racer accelerated from 0 m/s to 200 m/s in 5 s.  What was the acceleration?

• 0 m/s
• 40 m/s²
• -40 m/s²
• 40 m/s

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

Link between distance, time and speed

• average speed = distance / time
• average speed = time / distance
• average speed = speed / time
• average speed = distance x time
• average speed = distance / speed

The equation for finding average acceleration is

• (final velocity - initial velocity) ÷ time

• (initial velocity - final velocity) ÷ time

• initial velocity + final velocity + time

• initial velocity + final velocity - time

The equation for finding acceleration is

88 m/s north is

• Speed of object

• Velocity of object

• Acceleration of object

88 m/s²

• Speed of object

• Velocity of object

• Acceleration of object

72 m/s

• Speed of object

• Velocity of object

• Acceleration of object

The statement "A train travels 90 km in an hour" give the information about

• Speed of the train

• Velocity of the train

• Acceleration of the train

The statement "A storm is traveling 12 m/s eastward" give the information about

• Speed of the storm

• Velocity of the storm

• Acceleration of the storm
