Force & Motion

When the Net force is 0, which way will the object move?

• to the right

• to the left

• it will not move in either direction

The graph shows how far three runners were at different times of the race. During what part of the race did runner C move the fastest?

• 0 - 1.5 seconds

• 3 - 4.5 seconds

• 6 - 7.5 seconds

• 12 - 14.5 seconds

Allison is pushing a 70 pound box up a ramp. How does the ramp help her move the box?

• It increases the distance the box must move but decreases the force needed.

• It decreases the distance the box must move but increases the force needed.

• It increases both the distance the box must move and the force needed.

• It decreases both the distance the box must move and the force needed.

What unit of measuremen t do we use for force?

• Inches

• Meters

• Newtons

• Seconds

What are the 5 types of forces?

• magnetic, air pressure, friction, pushing, pulling

• contact, pushing, pulling, air pressure, gravitational

• magnetic, friction, gravitational, electrical, contact

Which scenerio matches the graph?

• A coach leaves the staion at 10am and arrives 11:30am. It stops here for 30 minutes and then carries on for another half hour, reaching its destination 40 kilomters later.

• A car travels at a constant speed for two hours. It then stops at the gas station for two hours and then continues on in heavy traffic for another two hours.

• A cyclist rides for two hours traveling at a constant speed. He then stops to rest for 30 minutes before continuing on for 18 miles.

• A cyclist rides for two hours traveling at a constant speed. He then stops to rest for 30 minutes before continuing on for 18 miles.
