Motion and Force
This is one type of friction.
What is
static,
sliding,
fluid, or
rolling?
An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an external force.
What is Newton's first law of motion?
the SI unit for measuring force
What is the newton?
A ramp is this type of simple machine.
What is an inclined plane?
a push or a pull
What is force?
For every action there is an equal and opposite reaction.
What is Newton's third law of motion?
the tendency of an object ot resist changes in its state of motion
What is inertia?
Simple machines make this easier.
What is work?
Gravity is an example of this type of force.
What is noncontact?
What is inertia?
the path that a projectile follows through space, due to the forces acting on it
What is its trajectory?
This simple machine consists of a bar that pivots on a fixed point, called a fulcrum.
What is a lever?
the resistance on object encounters while moving through a fluid, such as water or air
What is drag?
This is a term that describes Newton's second law of motion.
What is momentum?
What is potential energy?
This type of simple machine makes work easier by changing the direction of the applied force.
What is
a wedge,
a lever, or
a pulley?
"change in velocity"/"time"
What is acceleration?
Momentum = _?_ X acceleration
What is mass?
the energy of motion
What is kinetic energy?
What is work?
