Which of the following is the fundamental unit for a force?
Meter
kg*m/s
m/s^2
kg*m/s^2
m*kg^2
m*s/kg
Which of the following is Newton's Second Law?
An object at rest will remain at rest until acted upon by an outside, unbalanced force
Every force has an equal and opposite reaction force
Energy cannot be created or destroyed, only transferred from one object to another
The acceleration of an object is equal to the net force acting on it divided by the mass of the object
Which of the following is true for the force of gravity?
On Earth, it is always directed straight down, toward the Earth's center
It is always 9.8 m/s^2
It is also referred to as an objects 'weight'
It acts on all objects equally
Keeping everything else the same, if you double an object's mass, you double the force of gravity acting upon it.
What is the force of gravity acting on an object with a mass of 2.5 kg?
Hint: You can use 10 m/s^2 for the acceleration due to gravity.
The first blank is for the value. The second blank is for the units.
F =
The force of friction gravity normal tension compression( friction, gravity, normal, tension, compression ) is the force that resists all motion.
Put the appropriate forces in the correct spot for this object, a box acceleration to the right due to an applied force.
What is the net force acting on this object?
First blank is for the value. Second blank is for the units. Third blank is for the direction.
Net Force =
What is the net force on a object with the following forces acting upon it:
First blank is the resultant value. Second blank is the units. Third blank is the angle from the + x axis.
+x = 10 N - x = 13 N +y = 0 N - y = 4 N
R = @ degrees
is the force between all masses. is the force that resists all motion. is the force that resists an object being pulled into another object. It is always 90 degrees to its surface.

0.5 N
5 N
50 N
500 N
