Newton's Laws Vocabulary
Terms in this set (20)
Newton's First Law
An object will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Any push or pull that gives energy to objects and causes a change in motion.
The force that pulls objects towards each other; the greater the mass of an object, the greater the force of gravity on that object.
The effect of gravity on an object's mass.
An object falling under the influence of gravity; during free fall, all objects accelerate at the same rate regardless of mass, they will fall at exactly the same speed.
An upward force of air that opposes gravity; the greater the surface area, the greater the air resistance.
A force that one object puts on another when two objects rub past each other.
Occurs when solid surfaces slide over each other.
Occurs when an object rolls over a surface.
Occurs when an object moves through a liquid or gas; air resistance is a type of fluid resistance.
When two objects have an unequal force and/or mass; unbalanced forces start movement, stop movement, or change direction.
When equal forces acting on one object in opposite directions; balanced forces acting on an object will not change the object's motion; the total net force is zero.
Any force that causes an object to move in a circle acting towards the center of the circle.
Newton's Second Law
Acceleration is produced when a force acts on a mass. The greater the mass of the object, the greater the amount of force required to make it accelerate. Force can be measured by multiplying an object's mass by its acceleration.
The unit used to measure the amount of force. (Named after Sir Isaac Newton)
A change in speed or velocity, which also includes direction; speed is the rate of an object's motion; velocity is speed and direction of motion.
The strength of an object's motion; momentum = mass x velocity; the greater the mass of an object, the more momentum it has.
Newton's Third Law
For every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction.
An object that is thrown due to a force.
The path followed by a projectile flying or an object moving under the action of given forces.
