5th grade Force & Motion 5/1/24

The teacher sets up an experiment using containers like the ones shown below. Students observed and recorded the total time required to push two containers. Their results are shown below. Which variable is changed in this investigation?

• A. The number of trials

• B. The mass of the objects

• C. The force used to push the objects

• D. The type of timer used

Students investigate force. The setup the students used is shown below.

• Does the size of the object affect the total force needed to pull objects up a ramp?

• Does the height of the ramp affect the total force needed to pull objects up a ramp?

• Does the mass of the object affect the total force needed to pull objects up a ramp?

• Does the spring scale affect the total force needed to pull objects up a ramp?

Marisol has two toy cars attached to two elastic strings of the same length and material as shown below.

• Does the amount of force to pull each car affect the mass?

• Does the mass affect the distance each toy car travels?

• Does the thickness of the string affect the total force used?

• Does the force applied affect the length of the string?

Which of the following experiments would demonstrate how the mass of objects when pushed the same distance affects the total time traveled?

• Observe how far objects of different masses will travel when they are pushed by different amounts of force.

• Observe how much time it takes for objects of different masses to travel the same distance when pushed by different forces.

• Observe how far objects of the same mass will travel when they are pushed by different amounts of force.

• Observe how much time it takes for objects of different masses to travel the same distance when pushed by the same amount of force.

What is force?

• A push or pull

• A force that slows or stops an object in motion

• Energy

• Energy transferred from an object over a certain distance
