PS.8 Motion

A student sets up an investigation using a coin, a card, and a glass. The student removes the card quickly in the direction of the arrow, as shown.
The student observes that instead of traveling with the card, the coin remains in place and falls straight down into the glass. What concept of inertia did the student’s setup demonstrate?

• Unless an external force is applied to an object, it will tend to remain at rest.

• The greater the mass of an object, the more likely the object is to remain motionless.

• The greater the force, the farther an object will move.

• For every action, there is an equal and opposite reaction.

• 
  Lever and wedge

Newton’s first law of motion applies to objects that are —

• accelerating

• 
  in motion

• at rest

• 
  on other planets

Equal but opposite forces acting on an object results in—

• 
  no forces

• 
  change in an objects position

• balanced forces

• 
  unbalanced forces

"The net force of an object is equal to its force multiplied by its acceleration."
