Acceleration and Speed Worksheet

SPEED, VELOCITY & ACCELERATION

​

SPEED

• Speed is the measure how quickly distance changes with time..

• Average speed can be found by taking the total distance dividing by total time of travel

• Units for speed include mph with SI unit being m/s.

Multiple Choice

Find the speed of Sir Azwan’s car after 40 sec at 8 meters.

• 0.2 m/s

• 5 m/s

• 0.2 mph

• 40 mph

Using Equations to Solve for Speed, Distance, & Time

• Distance = speed x time

• Time = distance / speed

• Speed = distance / time

Multiple Choice

The average speed on 933 is 60mph and it is 30 miles from IISSA to Genting Highland. How long will it take to get to Genting Higland if I leave at 4pm?

• 5min

• 30 min

• 5hrs

• 30 sec

VELOCITY

• Velocity of an object is its speed combined with the direction of the motion

• Just add the direction to the speed and you have velocity

• An example of velocity would be 70m/s south

Multiple Select

Check the correct examples of velocity

• 6km/h

• 4 km/h north

• 70mph

• 70mph east

• 25 feet up

ACCELERATION

• A Change in motion caused by an unbalanced force acting on an object; includes increasing speed, decreasing speed or change in an objects motion.

Multiple Select

How are speed and velocity different?

• Velocity has direction plus speed

• Speed is scalar while velocity is vector

• change in position

• one is normal and one is weird

Multiple Choice

• 50 km/h

• 100 km/h

• 2 km/h

• 25 km/h

Multiple Choice

If a bicyclist travels 30 km in 2 hours, her average speed is

• 30 km/h

• 60 km/h

• 15 km/h

• 2 km/h

Multiple Choice

Aina cycles at an average speed of 8km/h. How far has she traveled if she cycles for 4 hours?

• 55km

• 32km

• 43km

• 32miles

Multiple Choice

It took 3.5 hours for a train to travel the distance between two cities at a velocity of 120 km/hr. How many km lie between the two cities?

• 34 km

• 420 km

• 120 km

• 360 km
