The type of force that can stop, start or change an object’s motion is known as —— force
Unbalanced
The calculation of mass times gravity will give the product of
weight
Friction always acts in a direction—to the direction that an object is moving.
opposite
To calculate the momentum of an object, you must multiply the mass time the
velocity
The amount of matter in an object is known as the objects
mass
Newton’s first law states that an object tends to resist a change in its motion. This is known as the objects
inertia
The unit kg x m/s/s is equal to one
Newton
If a force is balanced they are —- and ——- They object will not move in
this case.
equal and opposite
Every action has an equal and opposite reaction. This is known as Newton’s
3rd law
During ____________, gravity and friction are acting upon the object.
free fall
When 2 objects rub against one another, it is known as __________ friction.
sliding friction
