Force and Motion Ashleigh Farr

(2) Mrs. Giet’s class is playing tug of war at recess. They decide to play boys against girls. There are 11 girls and 6 boys. As soon as the game began, the girls were able to move the rope to their side. Why?

• There was an equal amount of force pulling on each side making it unbalanced.

• There was an equal amount of force pushing on each side making it unbalanced.

• There was more force on the girls side making it unbalanced.

• There was less force on the girls side making it unbalanced.

(3) Balanced forces have either a push or pull that is __________.

• Equal

• Unequal

• Hard

• Easy

(4) John was blowing a feather across the dinner table. When he was blowing with all the breathe he had in him the feather went across the entire table, but when he just blew a little it only went to the edge of his plate. What statement best describes why the feather went across the table?

• John used a strong blowing force causing the feather to travel a greater distance.

• John used a weak blowing force causing the feather to travel a greater distance.

• John used a pulling force to cause the feather to travel a greater distance.

• John is a fire breathing dragon.

(6) Stephanie was at the skateboard park at the top of a ramp. She was trying to decide which ramp to take her skateboard down. One ramp was 9 feet high and the other ramp was 5 feet high. She wanted to travel as far as she possibly could without having to use any pushing force. She chose the ramp that was 9 feet high. What statement explains why she chose the 9 ft. ramp to travel the greater distance?

• Stephanie knows the lower the incline the greater distance you will travel.

• Stephanie knows the higher the incline the slower you go.

• Stephanie knows the lower the incline the faster you go.

• Stephanie knows the higher the incline the greater distance you will travel.

(7) Which scenario is showing gravity as the main force moving an object?

• My pencil fell to the ground when I dropped it.

• A plane taking off.

• A feather floating in the wind.

• A boy threw a ball up in the air.

(8) A car was traveling on a dirt road and on a concrete road. The car was able to travel on the concrete road without using as much force. Which description explains this scientific fact?

• The dirt road has more friction because the surface is not smooth.

• The concrete road has more friction because the surface is smoother.

• The concrete road has more gravity because the surface is not smooth.

• The concrete road has less gravity because the surface is not smooth.

(1) Using a parachute causes a package to come to the ground slower. What statement explains this science fact?

• The package has less gravity because the parachute makes it smaller.

• The package has more gravity because the parachute catches wind and makes it heavier.

• The parachute causes air resistance and decreases the force of gravity on the object.

• The parachute causes air resistance and increases the force of gravity on the object.
