G6 UNIT 11 TEST - WORK, FORCE, ENERGGY

It took a snail 5 seconds to travel 10 inches. How fast was the snail moving?

• 2 mph
• 2 in/s
• 50 in/s
• 15 in/s

If a person walks 40 meters in 10 seconds how fast are they walking?

• 400 m/s
• 4 mph
• 4 m/s
• 50 m/s

What type of forces cancel each other out and do not cause motion to occur?

• Balanced forces
• Jedi forces
• Unbalanced forces
• Balanced porches

This picture is an example of what type of force?

• Friction
• Magnetic
• Gravitational
• Electric

What is a force?

• the PUSH or PULL on an object

• The MOTION an object creates

• The objects HITTING one another

• Going REALLY FAST

What is the net force?

• 40 N left
• 0 N Balalnced
• 400 N right
• 40 N right

What are 3 ways to describe MOTION? (Unbalance force causes this)

• Gravity, Magnetism, Friction

• Speed, Direction, Position

• Rough, Smooth, Lubricants

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is the formula to calculate speed?

• Speed = time/distance
• Speed = distance/time
• Speed = distance x time
• Speed = time x distance

According to the graph how far does the person travel in the first 5 seconds?

• 2 m
• 10 m
• 0 m
• 5 m
