Newton's 1st Law
What is Newton's 1st Law?
What is an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
what is quantitative description of the changes that a force can produce on the motion of a body
What is Newton's 3rd Law
What is when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object.
What is newton's third law of motion
What is another name for Newton's 1st law?
what is inertia
According to Newton's second law, this is why a small sports car gets better gas mileage than a large SUV.
What is mass resists acceleration

what is motion
An empty grocery cart and a full grocery cart are pushed with the same amount of force.
This is the cart (empty or full) that will accelerate more?
What is the empty cart?
When a girl jumps off a boat, she applies an ________ against the boat. The ________ is the force that the boat applies to the girl.
What is action force and reaction force?
Is a measure of how hard it is to stop a moving object.
What is momentum
What has to happen in order for an object to move?
what is a force has to be acted upon it
Mrs. Brown and Mr. Slight both throw a football of the same mass. According to Newton's second law, this is why Mr. Slight's football will accelerate more.
What is Mr. Slight has strength that can apply more force?
Each force acts on a different object.
What is why do forces not cancel out each other.
The total momentum of a group of objects stays the same unless outside forces act on the objects.
What is the law of conservation of momentum?
What happens to an object at rest if balanced forces act upon it?
What is the object remains at rest

What is 30 N?
When you jump, you push down on the ground, and the ground pushes up on you. When you swim, you push your arms against the water in the pool and the water in the pool pushes back on you in the opposite direction.
What are examples of Newton's third law of motion?
This is how much a 20 kg rope will accelerate when the purple team pulls with 85 N to the right and the silver team pulls with 105 N of force to the left.
