Newton
In object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.
newtons first law
the ability to do work
energy
two or more forces that are equal and opposite of one another; do not cause change in motion
balanced forces
If a force pushes a bow to the left with 15N of force, and another force pushes the box to the right with 25N of force, what is the net force?
10N of force
when you throw a ball in outer space, it will never slow to a stop.
true
An object will accelerate, depending on the object's mass, and the forces exserted on the object.
newtons second law
stored energy, energy ready to be released
potential energy
an object to start moving, stop moving, or change direction
unbalanced forces
What is the net force if a force is pushing a box to the right with 35N of force, and another force is pushing the bow to the left with 10N of force?
25N of force
You can move an apple with the same amount of force as a piece of paper to the same amount of acceleration.
false
For every action force, there is an equal but opposite reaction force
newtons third law
the energy of motion
kinetic energy
likely to maintain a state of rest unless acted upon by an external force
inertia
What is the net force when a force of 25N pushes a box to the right and a 10N force pushes the box the other direction?
15N
When you exert a force on an object, it exerts an equal force back.
true
Unit used to measure a force (N).
Newton
energy a substance or system has because of its motion
Mechanical energy
any change in the speed or direction of an object's motion
acceleration
What is the net force when 56N of force pushes a box to the right, and a force of 10N pushes the same direction?
66N of force
Friction and gravity cause an apple to eventually come to a stop when you throw it.
true
English mathematician and physicist; remembered for developing the calculus and for his law of gravitation and his three laws of motion (1642-1727)
Isaac Newton
energy a substance or system has related to its temperature
thermal energy
the resistance caused when one object is moved in contact with another
friction
What is the net force when 15N pushes a box down and 3N of force pushes the box the opposite direction?
12N of froce
In order to find the Net force, when all the forces on an object are balanced you subtract the force's amounts together.
