law of inertia
which is an example of inertia
a. doing a burn out
b. pulling a heavy box
c. a ball bouncing
d. scooting a chair back
all are correct
what's the second law of the laws of motion
the law of acceleration
what's the third law of the laws of motion
the law of action and reaction
How much force is needed to accelerate a 78 kg skier at 3 m/s2?
1. 234
2. 234m/s2
3. 234g
4. 234 N
4. 234 N
what's the first law of the laws of motion
the law of inertia
what is the unit of acceleration
meters per second square(m/s2)
Finish the quote: "for every there is action ..."
there is an equal and opposite reaction
What is the acceleration of an object with a mass of 80 kg being pushed with a force of 150 N?
1. 1.9 m/s
2. 1.88 m/s^2
3. 1.875 m/s^2
2. 1.88 m/s^2
Finish the quote: "an object in motion ..."
stays in motion
what is the formula for acceleration
a. f = m xa
b. a = f/m
c. m = f/a
b. a = f/m
which is an example of action and reaction and why
a. push off the ground on a seesaw
b. throwing a ball
c. moving a desk
a. push off the ground on a seesaw
you will go up in the air.
What is the mass of an object that is being pulled by a 1800 N force at 50m/s2?
1. 36 g
2. 48 g
3. 12 g
1. 36 g
Mass is a measure of
inertia
what is the formula for mass
a. m = f/a
b. m = f x a
c. m = a/f
a. m = f/a
which is an example of action and reaction and why?
1. pressing the brakes in a car
2. a plane flying in the air
3. closing a computer
1. pressing the brakes in a car
the car will end up stopping.
What is the force needed to move a 10,000 g object that is accelerating at 50 m/s2?
1. 500 N/s
2. 200 N
3. 350 N
2. 200 N
define inertia
the tendency to resist force/ movement
define the law
The more force applied to an object, the faster it will accelerate
define the law
•For every action, there is an equal and opposite reaction.
1.What is the acceleration of an object with a mass of 2100 kg being pushed with a force of 7500 N?
1. 3.57 M/S^2
2. 3.6 M/S^2
3. 4 M/S^2
1. 3.57 M/S^2
