1st Law
What is the 1st law of motion?
What is an object at rest stays at rest unless an outside force acts on it.
What is the 2nd law of motion?
What is the acceleration of an object is equal to the net force acting on the object divided by the mass.
What is the 3rd law of motion?
What is for every action there is an opposite and equal reaction.
You run into your friend while skating and both of you fall in opposite directions. This is an example of which law of motion?
What is Newton's 3rd law.
In the following example, what is the unbalanced force: A car is driving down the street, but comes to an abrupt stop when it hits a tree.
what is the tree
F = M * A Force = Mass x Acceleration. What formula is this?
What is Newton's 2nd law formula.
Explain how walking demonstrates Newton's 3rd Law.
Your foot pushes with a force down and backwards on the ground, and the ground pushes with a force up and forward on your foot, propelling you forward.
You are thrown off the front of a 4 wheeler when it runs into a fence. This is an example of which law of motion?
What is Newton 1st law.
Why do we wear a seat belt?
What is the cars brakes are designed to stop the cars forward motion, not yours. If the car stops suddenly, you will continue moving forward until your forward motion is stopped by the steering wheel, windshield or the ground. The seat belt applies a force opposite your motion and stops you.
Which would have a greater acceleration, a small car or a large car, if the same force is applied?
What is the small car.
A swimmer pushes off the side of the pool and is propelled forward by the force of the pool exerting a force on the swimmers foot. Explain this in terms of Newton's 3rd Law.
What is the action is pushing off of the side of the pool, the reaction is being propelled forward.
You left your book on a desk in Mrs. Buckalew's room and it is still there the next morning. This is an example of which law of motion?
What is Newton's 1st law.
Another name for Newton's First Law.
What is "law of inertia"
True or False: If an object is pushed with more force, it will move faster, or have a greater acceleration.
What is true.
If you push on a wall with 30 N of force, the wall will push back with how much force?
What is 30N
A car is easier to push than a bus. This is an example of which of Newton's Laws?
What is Newton's 2nd law.
Why did the penny fall into the cup when the index card was pulled away?
What is the quarter had inertia.
An object will _________________ in the direction that you push it.
What is accelerate.
