Force and Newton
A push or pull is what describes this.
What is the definition of force?
What are electrical forces?
Any two charged objects exert force on each other
The SI unit used to measure the strength of a force.
What is a Newton?
The greater an objects mass the __________ the force of gravity acts upon that object.
What is greater, more?
Was the scientist who came up with the law of universal gravitation
Who is Newton?
Newton's second law is:
What is acceleration of an object depends on the mass of the object and the amount of force applied?
What two factors effect electrical force?
What is charge and distance?
What is the difference between balanced and unbalanced forces?
What is when the forces on an object produce a net force of 0 and when the net force does not equal to 0.
As distance between objects decreases, the amount of gravitational force between them __________.
What is increases?
The object in space that sucks all of the gravity around it into itself, including light.
What is a black hole?
Newton's first law states....
What is an object at rest stays at rest, and an object in motion stays in motion at the same speed and direction, unless acted upon by and unbalanced force.
What is magnetic force?
When you bring two magnets together and they either exert a push or pull?
The amount of matter in an object?
What is mass?
Is the force that keeps the planets in an orbit around the sun.
What is gravity?
Which place would you have less gravitational pull, the Moon or Earth?
What is the Moon?
What is inertia?
What is the tendency of all objects to resist a change in motion?
What does the applied force on magnets do?
What is the force can either push the magnets apart or pull them together?
How much gravity is pulling down on an object.
What is weight?
The two factors that affect the gravitational attraction between objects are:
What is mass and distance?
As distance increases between objects, gravitational force (hint draw some arrows)
What is decreases?
What is Newton's third law?
What is whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
What is the difference between acceleration and speed?
What is acceleration is rate of which velocity changes and speed measures how quickly or slowly the object changes position.
States that the force of gravity acts between all objects in the universe
What is the law of universal gravitation?
The law of universal gravitation (p. 41) states what?
What is that gravity acts between all objects in the universe that have mass?
When you stand on a scale at the doctor's office the number displayed depicts the ____________that the Earth is exerting on you.
