Newton's First Law, Distance v Displacement

What is the result of balanced forces acting on an object?

• The object will start moving in the direction of the larger force.

• The object will accelerate.

• The object will change its shape.

• The object will not change its motion.

What does Newton's First Law, also known as the law of inertia, imply about an object at rest?

• It will remain at rest unless acted upon by a net force.

• It will eventually move due to natural forces.

• It will remain at rest as long as forces are balanced.

• It will move in random directions over time.

What is an object at rest?

• An object that is moving rapidly

• An object that changes its position over time

• An object that does not change its position over time

• An object that is used to determine the position of something else

What is a reference point?

• A point that moves with an object

• An object used to determine the position of something

• The exact location where an object is at rest

• The path an object follows when it moves

Which of the following would make for a good reference point?

• A flying bird

• A moving car

• A building

• A swimming fish

When is an object considered to be in motion?

• When it is used as a reference point

• When it does not change its position over time

• When it changes its position relative to a reference point

• When it remains at rest

What does Newton's First Law of Motion state?

• An object in motion stays at rest.

• An object at rest stays in motion.

• An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.

• An object in motion will come to rest eventually.

How many types of motion are there?

• 3

• 4

• 5

• 6

What is an example of linear motion?

• Rollercoaster over a hill

• Earth spinning on its axis

• Apple falling from a tree

• Pendulum on a clock
