What did Aristotle believe?
What is the rate at which an object falls depends on its mass.
100
Name 2 examples of projectile motion.
What is a frog leaping, a swimmer diving, answers may vary.
100
Does a heavier object experience greater gravitational force than a lighter object?
What is yes.
100
Name two examples that demonstrate Objects at rest.
What is a chair sliding, a golf ball hit off the tee, answers may vary.
100
What prevents objects in motion to move at a constant speed and in a straight line?
What is an unbalanced force.
200
What is the rate at which velocity changes over time?
What is acceleration
200
True or false. Vertical motion is parallel to the ground.
What is false, perpendicular.
200
What two things does acceleration depend upon?
What is force and mass.
200
What is the tendency of all objects to resist any change in motion?
What is inertia.
200
True or false. Action and reaction pairs are present when there is not motion.
What is true
300
What is the rate that all objects accelerate toward Earth?
What is 9.8m/s^2
300
What is an object in free fall?
What is when only gravity is the force acting upon it.
300
Are astronauts weightless in a space shuttle?
What is no.
300
What is Newton's second Law explain?
What is why objects fall to Earth at the same acceleration.
300
Why don't action and reaction forces in a pair act on the same object?
What is because the net force would always be 0N resulting in nothing moving.
400
What does each letter represent in the equation of a falling object?
What is t=time the object takes to fall in seconds G=acceleration due to gravity on Earth V=velocity
400
What is needed to keep objects in circular motion?
What is centripetal force.
400
What is the measure of gravitational force?
What is weight.
400
Summarize Newton's third law.
What is all forces act in pairs.
400
Does an object that has a small mass have less inertia than an object with a large mass?
What is yes.
500
What is net force equal to?
What is the force of air resistance subtracted from the force of gravity
500
What are the two components of projectile motion?
What is horizontal and vertical motion.
500
What is Newton's first law describe?
What is the motion of an object that has a net force of 0N acting upon it.
500
What equation represents Newton's second law?
What is F=m*a
500
When will acceleration increase?
What is when a larger force is exerted.
