Law's
What is Newton's first law of motion?
If the net force on an object is zero ,an object at rest will remain at rest and a moving object will continue moving in a straight line with constant speed.
It is the sum of all of the forces acting on an object.
What is net force?
F=M*A
Force =Mass x Acceleration
What is Newtons 2nd law of motion?
A fireman turns on a hose and is knocked backwards.
3rd law
All objects have inertia.
True.
Any object with mass has inertia.
What is another name for Newton's 2nd law?
The law of acceleration.
It states that all objects are attracted to each other by a gravitational force.
What is the law of Universal gravitation?
If two forces are going in the same direction how would you find the Net Force?
Add the two forces together.
A soccer ball will not move until it is kicked.
1st law
The standard metric unit of mass is the kilogram.
True.
How does Newton's third law of motion is differ from Newton's first laws of motion?
Newton's 1st law describes the forces acting on a single object.
Newton's 3rd law describes the forces between two objects.
It is the pull of gravity on an object.
What is weight?
Does a balanced cause an object to move?
No, it stays stationary.
Pushing a child on a swing requires less force than pushing an adult.
2nd law
Two common forces that prevents things from moving forever are?
Friction ,gravity.
What is Newton's second law of motion?
The acceleration of an object is equal to the net force exerted on the object divided by the object's mass.
It is the amount of matter in an object.
What is mass?
If a car travels 400m in 20seconds hw fast is it going?
20m/s
The air is let out of a balloon and it flies around the room.
3rd law
A skydiver falling through the air is an example of ____.
Air resistance.
What is newton's third law of motion?
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.
It is acting on an object that combine and form a net force of zero.
Balanced forces.
This is the standard unit used for describing the value of force.
Newtons.
A baseball continues to roll until friction, gravity, and air resistance stop it.
1st law
How is motion related to balanced and unbalanced forces?
Balance forces do not change the motion of an object; unbalanced force do.
