Adonis spins his little sister around in the air like a helicopter. He accidentally lets go of her hands and she goes flying. Which of Newton's Laws did he just demonstrate?
What is Newton's First Law - An object in motion/rest will stay at motion/rest unless acted on by an unbalanced force
200
If you have two objects with the same mass and you double the force on one of the objects, what will happen to the object's acceleration that is receiving double the force?
It's acceleration will DOUBLE
200
Name two forces that slow your motion as you are racing around a racetrack.
What is AIR RESISTANCE and FRICTION
200
What is the best description of balanced forces?
FORCES that are EQUAL in size and OPPOSITE in direction!!
200
What are the units for measuring weight?
What is NEWTONS because it is a force (or pounds)
300
Demetrios' car breaks down and he recruits some friends to help him push the car. If his car did not weigh so much it would not require as much force to move
What is NEWTON's 2nd LAW - Force = mass x acceleration
300
What is Rocky's acceleration if he has a mass of 45kg and is pushed with a force of 90N?
What is 2m/s/s
300
What is the force that balances gravity when an object is sitting on a surface?
What is NORMAL force
300
Matthew and Antonio are pulling Ronaldo in the same direction. Matthew has a force of 10N and Antonio has a force of 11N. Are the forces on Ronaldo balanced? Which way will he move and with what force?
UNBALANCED - he will move toward Antonio and Matthew with a force of 21N
300
Which will change if you travel to another planet (mass or weight)?
What is WEIGHT because it is affected by gravity
400
Ana pulls her friend Hailey on a scooter. Then the other Hailey jumps on. Ana cannot pull any harder and now the scooter is accelerating slower.
What is NEWTON's 2nd LAW - Force = mass x acceleration
400
You have two objects and one has double the mass of the other. You push both with the same amount of force. What happens to the acceleration?
The one with more mass accelerates half as much as the other.
400
Which of the following is the best example of balanced forces between FRICTION and TENSION? A -An orange hanging on a tree B - A sled rushing down a hill C - A boy pushing a wagon D - A monkey swinging from tree to tree
A- An orange hanging on a tree
400
Madelene and Michelle are fighting over Pierre. Madelene tugs on Pierre's right arm with a force of 9N and Michelle tugs on his left arm with a force of 5N. Are the forces balanced? With what force and in what direction will Pierre move?
UNBALANCED - Pierre will move toward Madelene with a force of 4N.
400
What is the force of weight on an object that has a mass of 10kg and an acceleration from gravity of 9.8m/s/s?
What is 98 N
500
Emma sees the boys from One Direction signing autographs across the room. She immediately accelerates from rest to a speed of 8m/s in 2s. If Emma has a mass of 36kg, what is the FORCE that she will collide with them?
What is 144N
500
Samantha sees the boys from One Direction. She immediately accelerates from rest to a speed of 8m/s/s in 2 seconds. She has a mass of 36kg. If she does not stop before she collides with Neil from the band, what will be the force that she collides with?
144N
500
Which example shows how friction and gravity can be unbalanced? A - a binder sitting on a table B - two equally strong teams pulling in a tug of war C - a roller skater moving at a constant speed D - a skydiver slowing down when he opens his parachute
D - a skydiver slowing down when he opens his parachute
500
Nathanial and Zyeina want the same jumprope. They both pull on the jumprope in opposite directions with a force of 150N. Are the forces balanced? With what force and in what direction will the jumprope move?
BALANCED - the net force is 0N and the jumprope should not move
500
