Students performed an experiment in which they rolled toy cars with different masses down the same ramp three times. What force could they be testing?
How the mass of a toy car affect the distance it travels. Gravity
100
a type of force that attracts objects of a certain metal to it.
Magnetism

A student uses a magnet to pick up small objects off the floor. Most likely, the objects are made of...
Iron, nickel, or cobalt

Spring Scale

A student gathers three identical balls, three identical ramps, and a meter stick. The student covers each ramp with a different material. By changing the surface over which a ball rolls, students could be investigate what force?
Friction
200
A push or pull
Force
200
True or False: when a door pushed open, it is moving in the same direction of the pushing force.
True
200
Force, in Newtons or grams

A student sets a block at the top of a wooden ramp. The student pushes the block. As the block slides down the ramp, it slows down and then comes to a stop. What conclusion can the student make about why this happened?
The force of friction was acting on the block as it slid down the ramp.
300
The attraction between two objects. Always a pull
Gravity
300
The bar magnet or the horseshoe magnet
The horseshoe magnet

A student drops a pencil and a marker, and they both fall to the floor. What causes both of these items to fall to the floor?
Gravity
400
A force that occurs when two objects rub together
Friction
400
Students are investigating how mass affects the force needed to move an object. They attach a wooden block to a spring scale, place a 10 g mass on top of the block, and pull it 50 cm across a tabletop.
As they do this, they observe the force shown on the spring scale. What should they do next in their investigation.
Repeat the same steps using the heavier mass.
