Any influence that tends to accelerate an object. A push or a pull; measured in Newtons.
The force that acts to resist the relative motion (or attempted motion) of objects or materials that are in contact. A force that works against the motion of an object
The fundamental SI unit of Mass.
A measure of an object's inertia. Also, a measure of the amount of matter in an object. Depends only on the amount of and kind of particles that compose an object - not on its location.
SI Unit of Force.
For an object at rest, it is the upward force that balances the weight of the object at rest. Also called a Support Force
For an object at rest, it is the upward force that balances the weight of the object at rest. Also called a Normal Force
The force on a body due to the gravitational attraction of another body (commonly the Earth). (*a downward force!*)
The quantity of space an object occupies
Newton's Second Law
The acceleration of an object is directly proportional to the net force acting on the object, it in the direction of the net force and is inversely proportional to the mass of the object. In other words... F=ma
Motion under the influence of gravitational pull only
The speed at which the acceleration of a falling object terminates because air resistance balances its weight.
Change in velocity divided by the time it takes for the change to occur
a relation between two quantities such that one increases in proportion as the other decreases.
A relationship between two quantities in which one increases as the other increases
frictional force air exerts on a moving object; acts opposite in direction to the object's motion. Depends on two things: speed and frontal surface area
The sum of all forces acting on an object. It is the net force that accelerates a mass (in the direction of the net force).
If an object is accelerating to the right, which direction must the friction point
The acceleration of an object is affected by which two forces?
Mass and net force
A 2kg object has an acceleration of 8m/s2.... What must be the net force acting on it?
An unbalanced force is also known as a
If an object is being pushed and its mass increases, then its acceleration must
If the net force applied to an object increases. Then its acceleration will
A 5kg suitcase falls out of a plane. When 50N of air resistance acts on it, what is its Fnet?
If the forces of an object are unbalanced, what kind of motion must it have?
A girl pulls her brother on a sled with a net force of 60N. What happened to its motion?
It speeds up
The boy gives a box a big push and then lets go. Friction acts against it. What's happening
It slows down
Which of the following affect Air Resistance on an object
Speed and frontal surface area
An object moves along a straight path. If the net force on it doubled, its acceleration would
Whenever the net force on an object is zero, its acceleration
Slide a book on its widest surface then, on its narrowest surface. Where is the friction greater?
What's the acceleration of a 10,000 kg jet that's being acted upon with 20,000 N of force
A skydiver jumps from a high-flying plane. As her velocity of fall increases, her acceleration
Net force and acceleration are
Which is normally greater: static friction or sliding friction on the same object?
What is the weight of a 10kg object on earth
What is the mass of a 60kg object on the moon
What is the weight of 500 grams of bananas
Acceleration is inversely proportional to
mass x acceleration
mass x gravity
