Fundamental Forces
What force pulls objects to the center of the Earth?
What is gravity?
Objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. This is Newton's _______ Law of Motion.
What is the 1st?
Maximum velocity reached by a falling object.
What is terminal velocity?
Mass resists ________________.
What is acceleration?
What is the force that opposes motion?
Who is friction
The unit of measurement for weight (force).
What are Newtons (N)?
For every action, there is an opposite and equal reaction. This is Newton's _______ Law of Motion.
What is the 3rd?
Acceleration is always in the direction of the _______ ____________.
What is net force?
The quantity of matter in an object.
What is mass?
True or false, there is no gravity in space?
What is false. Gravity is much less in space, but gravity is always present.
What physical property determines inertia and gravity?
What is mass?
The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object. This is Newton's _______ Law of Motion.
What is the 2nd?
What is acceleration?
What is the rate of change of velocity?
An object's resistance to a change in motion.
What is inertia?
Who discovered the laws of motion?
Who is Isaac Newton
The force upon an object due to gravity.
What is weight?
Newton's First Law of Motion is also known as the Law of ____________.
What is inertia?
Acceleration is _______________ _______________ _______________.
What is speeding up, slowing down, changing direction?
What is the relationship between inertia and mass?
What is directly proportional?
Causes an object to start or stop moving, accelerate or change direction.
What is an Unbalanced Force
Liquids and gases are also known as ____________.
What are fluids?
Objects with more mass fall faster than objects with less mass.
What is false?
What causes acceleration?
What are unbalanced forces?
Amount of space an object takes up (it's size).
What is volume?
What is the momentum of an object that has a mass of 50 Kg traveling at a velocity of 30 m/s?
1500kg/m/s
