Any two masses that exert an attractive force on each other
Gravity
An object in motion stays in motion, or an object at rest stays at rest until an unbalanced net force acts upon it.
Newton’s First Law of Motion
The greater the object mass, the _______ the gravitational force on it.
stronger
What is the formula for Newton's Second Law ?
Force = mass x acceleration
A gravitational force exerted on an object; measured in units called
Newtons
Anything that is thrown or shot through air is called?
Projectile
What two things does Gravity depend on?
Mass and Distance between objects
Projectiles follow a curved path and has __________________ motion and ___________ motion.
Horizontal and Vertical
Which law is a Tennis ball bounces to the ground?
Newton's Second Law. The mass of a tennis ball is constant so the acceleration of a tennis ball is directly proportional to the force applied by the player. The harder you hit, the faster the ball will go
A net force acting on an object causes the object to accelerate in the direction of the force.
Newton’s Second Law of Motion
What does Centripetal mean?
“centripetal” means toward the center
The property of moving object resulting from its mass and velocity.
Momentum
Extra Credit:
A force acting toward the center of a curved or circular path
Centripetal force
For every action (or force), there is an equal and opposite reaction (or force).
Newton’s Third Law of Motion
The tendency of an object to resist any change in its motion.
Inertia
