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
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
What is this item called?
Spring Scale
On the playground, what is a way that you can test out friction?
Accept reasonable answers
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
A push or pull
Force
True or False: when a door pushed open, it is moving in the same direction of the pushing force.
True
What does this tool measure? In what units?
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.
The attraction between two objects. Always a pull
Gravity
A magnet is laid on a ruler on the centimeter side. A paperclip is placed on the opposite side of the ruler and is slowly moved toward the magnet. What are you testing?
How many centimeters does the magnet take to attract the paperclips
Looking at the diagram, which magnet is stronger?
The bar magnet or the horseshoe magnet
The horseshoe magnet
What force pulls things down to earth?
Gravity
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
A force that occurs when two objects rub or come into contact with each other
Friction
A horseshoe magnet and a bar are placed at the end of two different rulers. A car with a magnet on top is placed on the opposite side of the rulers. For the horseshoe magnet, the car began moving when the magnet was 12 centimeters away. For the bar magnet, the car began moving when the magnet was 5 cm away. Which magnet was strongest?
The horseshoe magnet
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.
A pulling force makes things move ___________ whatever is doing the pulling.
towards
A person is testing how mass affects the force needed to move an object. They use a spring scale and an object weighing 50 g. What should be changed in order to make a valid experiment?
Add more mass to the object
Something that you change in an experiment
Variable
If you put 2 magnets with like poles facing each other, they will...
Repel each other
We used this to measure how far the car traveled after rolling on different surfaces.
meter stick (centimeters)
A pushing force moves things ___________ from whatever is doing the pushing force.
away
