Forces and Newton's Laws
Contact and Non-contact (Field) are two general types of this physical vector quantity.
What are Forces?
The single force that is the VECTOR SUM of all the individual forces acting on an object.
What are Net Forces?
The standard units used to measure acceleration (a).
What is m/s2 (meters per second squared)?
What is g?
The distance from the center of the circular path to the object?
What is Radius (r)?
The force transmitted through string, rope or a cable when pulled tightly.
What is Tension Force?
The unit of measurement for Force (F) in the metric system.
What is Newton (N)?
The combination of horizontal and vertical motion.
What is projectile motion?
What does the variable Xf represent in horizontal and vertical motion?
What is final position?
The force needed to keep an object moving in a circular path that is always directed inward.
What is centripetal force?
This law is often called the Law of Inertia, describing an objects tendency to resist changes in its motion.
What is Newton's First Law of Motion?
The fundamental force that acts between any two objects with mass.
What is Gravity, What is Gravitational Force?
This is the constant acceleration value for any object in FREE FALL near the Earth's surface.
What is Gravity's constant, what is 9.8 m/s2 ?
The shape of the path taken by a projectile in the air.
What is a parabola?
The time it takes for an object to make one complete full rotation around a circle.
What is Period (T)?
The formula that mathematically relates net force, mass, and acceleration.
What is F=MA?
Give me 3 types of Field Forces.
What are Gravity, Electrostatic, Magnetic, or Nuclear forces?
The kinematic formula used to find displacement when initial velocity, time, and acceleration are known.
What is d= vi t + 1/2 at2 ?
The formula vf = vi + at is used to find this quantity.
What is final velocity?
This is the instantaneous linear velocity of an object in circular motion where direction is tangent to the circular path and perpendicular to the acceleration vector.
What is tangential velocity?
A rocket pushes hot exhaust gases downward, and the gases push the rocket upward with an equal force, propelling it into space. This is an example of what law of motion.
What is Newton's 3rd Law of motion/Law of action-reaction?
The calculated Net force acting on a 5 kg block accelerating at 3 m/s2 ?
What is 15 N? F=MA : F= 5kg X 3 m/s2
The instantaneous velocity of an object thrown straight up at the moment it reaches its maximum height.
What is zero (v= 0 m/s)?
What would happen to an objects falling without air resistance in a vacuum?
What is objects falling at same rate regardless of mass?
Imagine you are laying in bed and you are staring at ceiling fan in your bedroom. You suddenly remember your amazing physics class, and when we talked about acceleration. What are the 3 conditions for acceleration to happen and knowing this is the ceiling fan acceleration?
What is change in speed (slowing down/speeding up) and change in direction and yes the fan is accelerating because it is changing direction?
