forces & newtons first law

What is Newton's First Law known as? The Law of

• Friction

• Mass

• Inertia

• Gravity

What is Newton's First Law

• F=ma

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion. 

• Friction 

The tendency of an object to resist a change in its motion

• acceleration

• inertia

• mass

• frame of reference

Balanced or unbalanced?

• balanced

• unbalanced

Which has more Inertia? (so need more force to move) 

• Truck

• Ant

• A cat

• A skateboard

Which type of force(s) will cause a change in an object's motion?

• gravity

• zero net force

• balanced forces

• unbalanced forces

Galileo found that a ball rolling down one inclined plane would roll how far up another inclined plane? 

• The ball would not rull up the other plane at all. 

• to nearly the original height

• to nearly twice the original height. 

• to nearly half it original height

Which way is the object moving?

• it's either not moving or moving at a constant speed due to balanced forces

• to the right

• to the bottom

• up

With unbalanced forces, the object will move in the direction of the _______ force.

• larger 

• smaller 

• equal 

A bowling ball is rolled across the parking lot. Which statement about it is true?

• the bowling ball will only stop if it strikes something

• the bowling ball will never stop

• the bowling ball will eventually stop because of friction

• the bowling ball will eventually stop because of inertia
