Students conduct experiments to investigate friction. Which experiment will best test the effect of friction on objects?
Drop two balls from the same height at the same time
Roll two marbles on the carpet from the same starting point at the same time and with the same amount of force
Roll three marbles across three different surfaces from the same starting point at the same time and with the same amount of force
Release two balls from the top of a ramp at the same time
Students investigate force. The masses they use begin at rest on the ramp. The setup the students use is shown. Which change will reduce the amount of force needed to move the masses?
Decrease the height of the ramp
Increase the height of the ramp
Add an additional mass
Pull the spring scale with two hands
Which question is the student most likely trying to answer with this investigation?
How many spaghetti noodles will it take to hold up the mass of a penny?
How much force will it take to break the spaghetti noodle?
How long should the string that holds the paper cup be in order to support the greatest mass of pennies?
How does the distance between the two chairs affect the amount of force it takes for the spaghetti noodle to break?
Which statement correctly describes the forces that affect the student's position and motion?
The force of gravity causes the student to speed up from Position A to Position B.
The force of gravity causes the student to speed up from Position B to Position C.
The force of the student’s legs moving causes the motion to stop at Position B.
The force of the student pulling on the swing causes the motion to stop at Position A.
Which statement best describes the motion of the car when the straw is released?
The car will move away from the wall in the same direction as the air that is leaving the balloon.
The car will move toward the wall because of the force of the air from the straw.
The car will move fast because the straw gets light as the air is released.
The car will not move because the air escapes from the balloon.
What force causes the wagon to stop?
The force of gravity which is acting in the same direction as the arrow
The force of friction which is acting in the same direction as the arrow
The force of gravity which is acting in the opposite direction of the arrow
The force of friction which is acting in the opposite direction of the arrow
Which actions will make moving the cart in one direction easiest for the students?
Student 1 pulls the cart to the left while Student 2 pulls the cart to the right.
Student 1 pulls the cart to the left while Student 2 pushes the cart to the left.
Student 1 pushes the cart to the right while Student 2 pushes the cart downward.
Student 1 pushes the cart to the right while Student 2 pulls the cart upward.
Which experiment would best demonstrate the effect of surface area on friction?
Roll a marble on a smooth surface and a rough surface and compare the distances traveled
Push a toy car on a flat surface and an inclined surface and measure the speed
Drop a feather and a stone from the same height and observe their fall
Slide a large book and a small book down a ramp and measure the time taken to reach the bottom
What change would most likely increase the speed of a toy car rolling down a ramp?
Reduce the mass of the toy car
Decrease the angle of the ramp
Increase the mass of the toy car
Use a rougher surface on the ramp
Which factor would most likely affect the distance a ball rolls on a flat surface?
The color of the ball
The texture of the surface
The shape of the ball
The temperature of the room
