Newtons First Law
This law says an object at rest stays at rest and an object in motion stays in motion unless acted on by a force
Newton's first law
Mass is technically defined as
The amount of matter inside of an object
What is Friction?
A force that opposes motion between two surfaces that are touching.
For every action force there is a what?
Opposite and equal reaction force
What do we call the total force acting on an object?
Net Force
This word means an object resistance to changing its motion
Inertia
Kilograms or grams
What is the sum of all forces acting on a object
Net force
When you jump off the ground what pushes you upward
If the net force on an object is 0, what happens to its motion.
An object at rest stays at rest and an object in motion stays in motion stays in motion unless acted on this type of force
Unbalanced Force
Earth's gravitation pull has an acceleration of?
9.82m/sec squared
What is Newton's second law of motion formula (Force)
F=MA
Force=Mass x Acceleration
A rocket launches because gases push downward. What pushes the rocket upward.
Reaction force of the gases.
2 forces act on a box, 8N right and 8N left. What's the net force?
0N
A hockey puck sliding on ice keeps moving because there is very little of this force slowing it down.
Friction
3.73m/sec squared
Gravity
When a swimmer pushes water backwards, what happens?
Move forward
A 20N force pushes right and a 5N force pushes left. What is the net force?
15N to the right.
Which law explains " When two bodies interact, the forces exerted by each body on the other are always equal in magnitude and opposite in direction.
A 10kg object has a net force of 20N acting on it? What's the acceleration?
2m/s squared
What is tension and what example can you use from it
A gun recoils backward when fired. What force causes this recoil
The bullet. Pushes forward and the force pushes the gun backwards.
An object has balanced forces acting on it. What is it acceleration?
0m/s squared
