What is the equation for Force?
velocity x motion
mass x acceleration
kilograms x mass
meters / seconds
The combination of all forces are called
balanced forces
total force
net forces
When there is a change in an object's motion, what is caused?
balanced force
net force
unbalanced force
When forces are equal from both sides, this is called...
unbalanced force
balanced force
gravity
acceleration
What is Newton's SECOND law?
For every action there is an equal and opposite reaction
If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.
An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.
What is Newton's THIRD law?
For every action, there is an equal and opposite reaction
An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.
If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.
Which statement below predicts what will happen in the situation ?
Box will move to the right because the force are unbalanced
Box will move to the left because the force are balanced
Box will not move because the force are unbalanced
Box will not move because the force are balanced
What is the net force on the box shown above
10 N to the left
10 N to the right
70 N to the right
60 N to the left
What is the speed at point B?
1 m/s
2 m/s
0 m/s
10 m/s
What is happening in section B?
the object has stopped moving
the object is moving at a constant velocity
the object is accelerating
I forgot
In what direction does friction act?
opposite the direction of motion
perpendicular to the direction of motion
in the same direction as motion
down
A force of 15N==> acts on a mass of 10kg. What will be the acceleration?
150 kg*N ==>
150 kg*N
1.5 m/s
1.5 m/s2 ==>
Describe the motion in the graph:
Constant Speed (positive slope)
Stopped (at rest)
Acceleration (increasing speed)
Return Home (negative slope)
Describe the motion in the graph:
Constant Speed (positive slope)
Stopped (at rest)
Acceleration (increasing speed)
Return Home (negative slope)
Match the description to the graph:
"The speed of the car is decreasing."
What force is acting on the cat at the end?
