Newton's Law
Flashcards with questions about Newton's Laws and Simple Machines
Question | Answer |
---|---|
What is Newton's 1 Law of Motion? | An object can be in rest or an object can be motion unless a unbalanced or exerted force stops or slows it down. |
What is an example of Newton's 1 Law of Motion | You are riding on a skateboard and pieces of gravel start to be on the road and then the skateboard stops and cannot go any farther. |
What is Inertia | Inertia is the tendency of all matter to resist any change in motion. |
What is Newton's 2 Law of Motion? | An object will accelerate unless an unbalanced force pushes it |
What does Newton's 2 Law of Motion depend on? | Its acceleration depends on the size of the force and the mass of the object |
What is Newton's 2 Law of Motion Formula? | Force = mass x acceleration or F=ma |
What is Newton's 2 Law of Motion's Sentence? | The more mass an object has, the more force you need to accelerate it. |
What is an example of Newton's 2 Law of Motion? | One box with stuff the force equals 10N and the other is an empty box and the force equals 5N and more force is needed to accelerate the heavier box. |
What is Newton's 3 Law of Motion? | Every Action Has An Equal And Opposite Reaction. |
What is the action and reaction of a rocket? | Action: Gas pushes down and out back of the rocket Reaction: The rocket goes up |
What is the action and reaction of a man pushing a wall? | Action: The man is pushing the wall Reaction: The wall is exerting the same force back |
What is the action and reaction of the girl swimming? | Action: Her foot is pushing against the wall Reaction: She will travel forward |
What is the action and reaction of a balloon? | Action: Air is coming out of the balloon Reaction: The balloon will fly in the opposite direction |
What is an inclined plane? | An incline plane is a sloped surface, such as a ramp |
What are some examples of a inclined plane? | Staircase, ramp, bottom of a bath tub, etc. |
What is a screw? | A screw is when a incline plane is wrapped around a cylinder shape |
What is an example of a screw? | An example of a screw is a bolt, spiral staircase, etc. |
What is work? | Work is the action that results when a force causes an object to move in the direction of the force. |
What is the work formula? | The work formula is Work = Force x Distance |
Does simple machines reduce the amount of WORK? | Simple Machines do not reduce the amount of work, it just makes the work easier. |
WORK sentence trick | If the object does not move then no work is being done! |
