Friction
In general, in which direction does the force of friction act?
This is the sum of all forces acting on an object.
What is net force?
Name an example of a non-contact force
Gravity
Electrostatic
Magnetic
This law states that objects tend to resist changes in their motion.
What is Newton's First Law?
This is the transfer of energy when a force moves an object.
What is work?
This type of friction occurs when an object is resting still on another surface
Static Friction
When forces are equal and opposite, they are said to be this.
What is balanced?
If the mass of objects increases, the gravitational force will do this.
What is increase?
This equation represents Newton’s Second Law.
What is F = ma?
This unit is used to measure energy.
What are joules (J)?
This type of friction occurs between two objects or surfaces that are sliding past each other.
Sliding friction
When forces do not cancel each other out, they are this.
What is unbalanced?
If objects move farther apart, gravitational force will do this.
What is decrease?
An object has a mass of 10 kg and experiences a force of 10 N. What is it's acceleration? Include units.
1 m/s2
This type of energy is due to the motion of an object
What is Kinetic Energy?
Air resistance is this type of friction
Fluid friction
Balanced forces result in this kind of motion.
What is constant speed/velocity?
This is a measure of the gravitational force acting on an object.
What is weight?
State Newton's Third Law.
What is "For every action there is an equal and opposite reaction"?
(note: wording may vary)
This type of energy is stored when an object is stretched or compressed.
What is elastic energy?
Friction results in an increase in this type of energy
Thermal Energy (heat)
Unbalanced force results in this kind of motion
What is acceleration?
This is the maximum speed at which an object can freefall on earth.
What is terminal velocity?
Normal force is an example of this law of motion.
What is Newton's Third Law?
