define the following terms in your science notebook. due tuesday 9/16:

• acceleration
• centripetal acceleration
• displacement
• momentum
• motion
• speed
• velocity
• air resistance
• centripetal force
• field
• force
• free fall
• friction
• gravity
• net force
• newton’s first law of motion
• newton’s second law of motion
• newton’s third law of motion
• terminal velocity
• weight

Explanation:

Acceleration: Rate of change of velocity.
Centripetal acceleration: Acceleration towards the center in circular - motion.
Displacement: Change in position with direction.
Momentum: Product of mass and velocity.
Motion: Change in position over time.
Speed: Distance traveled per unit time.
Velocity: Speed with direction.
Air resistance: Force opposing motion through air.
Centripetal force: Force causing centripetal acceleration.
Field: Region where a physical quantity has a value at every point.
Force: Push or pull that can change motion.
Free fall: Motion under the influence of gravity only.
Friction: Force opposing relative motion between surfaces.
Gravity: Attractive force between masses.
Net force: Vector sum of all forces acting on an object.
Newton’s first law of motion: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton’s second law of motion: Force equals mass times acceleration ($F = ma$).
Newton’s third law of motion: For every action, there is an equal and opposite reaction.
Terminal velocity: Constant velocity when air resistance equals weight.
Weight: Force due to gravity acting on a mass ($W=mg$).
