Force and Motion Study Cards

What is Newton's First Law?

• An object at rest stays at rest and an object in motion stays in motion at same direction and speed unless acted on by an unbalanced force

• Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object

• For every action there is an equal and opposite reaction

What is Newton's 2nd Law?

• An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force

• Acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object

• For every action there is an equal and opposite reaction

What is the 3rd Law of Motion?

• For every action there is an equal and opposite reaction

• An object at rest stays at rest and an object in motion stays in motion

• Acceleration is produced when a force acts on a mass

If the same amount of force is applied to a few objects, the object that has the ____________ amount of mass will move the farthest.

• Most

• Same

• Least

What causes all the forces on an object to cancel one another out which means there is NO movement?

• Unbalanced forces

• Balanced forces

• Forces don't cancel each other out

• There is always movement

What force pulls objects down to Earth?

• balanced forces

• unbalanced forces

• gravity

Which has the least amount of friction?

• sandy beach

• ice skating rink

• asphalt road

• forces

Which requires more force to move?

• a solid metal chair because it has more mass

• a plastic chair because it has less mass

If you want to move two identical objects A and B in the same direction, but want to move object A further, what must you do?

• exert more force on object A

• exert more force on object B

• exert the same amount of force on both A and B

What is the unit of gravitational force called and how is it measured?

• Newton, spring scale

• Brady, spring scale

• Harvey, spring scale

• Force, spring scale
