Distance, time, speed and velocity notes check

Speed is the ____________ travelled by an object in unit time.

Distance =

• s/t

• s x t

• t/s

• m/s

Something has constant or uniform speed if it travels equal distance in equal intervals of time.

• True

• False

Which is true?

• Speed has direction, velocity does not.

• Velocity has direction, speed does not.

• Neither velocity or speed have direction.

• Speed and velocity are both scalar.

How far in meters can you brother get if he travels at 2.5 m/s for 5 seconds?

How much time in seconds will it take a bug to travel 5 meters if it is travelling at 1 m/s?

What is your speed in meters per second if you move 50 meters in 10 seconds?

When the velocity of an object decreases, this is called __________________.
