02 Newton's Laws PRE-assessment

LT#1: Which of the following best describes Newton's FIRST law of motion?

• F=m x a

• An object in motion stays in motion unless acted upon by an outside force

• Acceleration in produced when force acts upon a mass

• For every action there is an equal and opposite reaction

LT#1: According to Newton's first law of motion, an object in motion...

• stays in motion

• stays at rest

• slows down

• always accelerates

LT#1: According to Newton's first law of motion, an object at rest...

• stays in motion

• stays at rest

• will never accelerate, even with an outside force

• will have the greatest kinetic energy

LT#1: Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces acted upon it.

• Newton's FIRST law of inertia

• Newton's SECOND law of acceleration

• Newton's THIRD law of action-reaction

LT#1: Which key idea is most related to Newton's FIRST law of motion?

• friction

• acceleration

• action-reaction

• inertia

LT#2: Which of the following is an example of Newton's FIRST law of inertia?

• Leaning back against a chair and the chair pushes back

• Kicking a ball and the ball pushes against your foot

• Pushing a shopping car that is still and it rolls forward

• Hitting a baseball with a bat that vibrates and hurts your hand.

LT#2: Newton's FIRST law of motion states that an object at rest will stay at rest unless acted upon by an outside force. Which activity is an example of this law?

• A football is kicked off of a tee.

• A baseball player slides into second base.

• A floating stick is carried over a waterfall.

• A bicycle travels faster as it goes downhill.

LT#2: Place a ball in a box and slowly push the box forward. Abruptly stop the box. The ball will...

• keep moving forward

• not move

• move backwards

• gain mass

LT#2: According to Newton's first law, if rocket is launched into space it will...

• move in the same direction until affected by an outside force

• change acceleration based upon the mass of the rocket

• slow down once it reaches outer space

• not move because there is no external forces in space

LT#2: A truck brakes hard and the large pile of stone in the back continues to move forward. This is an example of....

• Newton's FIRST law

• Newton's SECOND law

• Newton's THIRD law

• Newton's FOURTH law
