Newtons 1st law: inertia

An object at rest stays at rest unless acted on by an ____________ force

Multiple Choice

An objects tendency (likelihood) to resist a change in motion _________

• inertia

• friction

• gravity

• unbalanced forces

Multiple Choice

How will you move/accelerate an object at rest?

• exert a balanced force

• exert an unbalance force

• nothing

Multiple Choice

The card is pulled from the cup, and the coin falls into the cup. Which of the following best explains this scenario

• the coin was at rest and will stay at rest due to inertia. gravity was the force that made the coin fall into the cup

• the card being pulled from the cup causes the coin to move also

• the unbalanced force of the pull of the card made the coin have an unbalanced force as well causing it to change motion

Multiple Choice

Newtons 2nd Law: law of force and ___________

• force

• acceleration

• inertia

• action reaction

Multiple Choice

According to newtons 2nd law of motion, the greater the mass of an object the greater the force needed to change its motion.

• true

• false

Multiple Choice

According to newtons 2nd law of motion, the more force applied to an object the ____________ the acceleration.

• greater

• lesser

• none of the above

Multiple Choice

The formula to calculate acceleration is

• F=ma

• a=F/m

• m=F/a

• a=Fm

Multiple Choice

Which cart would accelerate the least?

• A

• B

Multiple Choice

The examples in the images represent newtons 3rd law of motion. Which of the following best represents newtons 3rd law?

• an object at rest will remain at rest unless acted on by an unbalanced force

• the greater the mass of an object the lesser the acceleration

• for every action there is an equal and opposite reaction force

• heavier objects have a greater inertia

Multiple Choice

Newtons 3rd law is:

• Action & reaction

• force and acceleration

• mass and force

Multiple Choice

Newtons law states that for every action, there is an_________ reaction

• unequal and opposite

• stronger and opposite

• equal and similar

• equal and opposite

Multiple Choice

Force always come in________

• waves

• triplets

• pairs

• 2

• 3

• All of the above

Open Ended

When a rocket launches, the exhaust from the engine pushes on the ground and the ground pushes the rocket upwards. What is the action force?

Multiple Choice

A magician pulls a tablecloth from under a set of dishes. When the tablecloth is pulled, the dishes remain on the table. According to newtons 1st law of inertia, why do the dishes not fall off of the table?

• The magician is very talented and moved the tablecloth quickly.

• There was no force applied to the dishes, so they will remain at rest due to inertia.

• The mass of the dishes caused them to stay on the table.

• The force of gravity caused them to be pulled down quickly before they fell off of the table.

Multiple Choice

The man in the car slammed on his breaks. He then lunged forward in his seat. According to newtons first law, an object in motion will remain in motion until acted on by an unbalanced force. What is the reason for him lunging forward in his seat?

• friction

• gravity

• inertia

• his mass

Multiple Choice

• 5m/s/s

• 5m/s

• 50N

• 50m/s
