Forces and Motion Concepts Assessment

Susan Morris introduces STEMscopes and guides a class through experiments on forces, gravity, and magnetism. The video demonstrates how gravitational pull affects objects and how magnets interact with different materials. It explains the concepts of forces, motion, and friction, and highlights the presence of magnetism in everyday items.

What are the three types of forces discussed in the introduction?

• Gravity, Electricity, Magnetism

• Gravity, Friction, Magnetism

• Friction, Electricity, Gravity

• Electricity, Magnetism, Friction

Which materials were used in the experiment to learn about forces?

• Tape, ruler, string, paper clips, binder clip, pipe cleaner, rubber bands

• Tape, ruler, string, paper clips, binder clip, pipe cleaner, glue

• Tape, scissors, string, paper clips, binder clip, pipe cleaner, magnets

• Tape, ruler, string, paper clips, binder clip, pipe cleaner, magnets

What causes objects to fall towards the Earth?

• Wind resistance

• Frictional force

• Gravitational pull

• Magnetic pull

Why do objects with more mass experience a greater gravitational pull?

• They are closer to the Earth

• They have a larger surface area

• They have more mass

• They are denser

At what distance did the magnet attract the paper clip during the experiment?

• 1 inch

• 2 inches

• 2.5 inches

• 1.5 inches

Which item had the least mass in the magnetic attraction experiment?

• Binder clip

• Pipe cleaner

• String

• Paper clip

What is the role of friction in motion?

• It speeds up objects

• It has no effect on objects

• It slows down objects

• It changes the direction of objects

How does friction help us in everyday life?

• It reduces the wear and tear of objects

• It increases the speed of cars

• It helps us walk without sliding

• It makes surfaces slippery

Which everyday objects contain magnets?

• Television, refrigerator, microwave

• Washing machine, dryer, dishwasher

• Laptop, tablet, camera

• Doorbell, remote control, cell phone

What should you do to further investigate forces at home?

• Use magnets and rulers with household items

• Read books about forces

• Watch videos about forces

• Write a report on forces
