5.6D Forces

Front

What other piece of equipment would be most useful for an experiment testing the force of a spring using a spring launcher and four spheres with the same diameter but different masses?

Back

A meter stick to measure the height each sphere reaches after the sphere is launched

Front

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk, carpet, sandpaper, and glass. What is a reasonable conclusion?

Back

Smoother surfaces will decrease the amount of force needed.

Front

A student designs an experiment to test the force of a spring using a spring launcher and four spheres with the same diameter but with different masses. What question is being asked in this investigation?

Back

How does the mass of the ball affect the force needed?

Front

A student designs an experiment to test the force of a spring using a spring launcher and four spheres with the same diameter but with different masses. What is a reasonable conclusion to this investigation?

Back

More mass will require more force to launch the ball.

Front

In an experiment to study crater formation using marbles and flour, what is the variable?

Back

The height the ball is dropped.

Front

Students drop the same heavy ball onto identical blocks of soft clay from different heights. For each height they measure the depth of the dent the ball makes in the clay. What question could we use this investigation to answer?

Back

How does the height affect the size of the crater?

Front

Why can't we find an answer to the investigation about the effect of elastic width on stretchability?

Back

There are 2 variables - elastic width and mass.

Front

The diagrams show two trials of an experiment in which a spring scale was used to measure force. What is the difference between the two trials?

Options: The mass, The surface of the table, The angle of incline, The type of book used

Back

The mass

Front

What are the students testing to see if it has an effect on the force needed to move the book? Options: Friction, Angle of Incline, Mass, Density

Back

Mass

Front

What is the variable that should change in an experiment to determine how much force is needed to move blocks of wood of different masses across a lab table?

Back

Mass of wood block
