Types of Forces
A force that requires the objects to be physically touching each other.
What is a contact force?
The equation for net force on an object.
What is Fnet=ma?
The net force exerted on a 7kg object accelerating at a rate of 4m/s2.
What is 28N?
A measurement of an object's resistance to change in motion.
What is inertia?
The difference between an object final and initial positions.
What is displacement?
A force that is exerted by a rope, cable, or string.
What is tension force?
The equation for gravitational force exerted on an object near the earth's surface.
What is Fg=mg?
The spring force exerted by a spring with a spring constant of 400N/m that has been compressed 0.25m.
What is 100N?
An object at rest will remain at rest and an object in motion will remain in uniform motion unless acted upon by an unbalanced force.
What is Newton's First Law of Motion?
The kinematics equation that relates displacement, initial velocity, acceleration, and time.
What is x=vit + (1/2)at2?
A force that acts to prevent objects from moving through a surface.
What is a normal force?
What is Fs=kx?
The acceleration of a 5kg object that is experiencing a 40N force to the left and a 100N force to the right.
What is 12m/s2 to the right?
In order to experience a change in motion, an object must experience this.
What is an unbalanced force?
The final velocity of an object that starts at a speed of 15m/s, then slows down at a rate of 2m/s2 for 3 seconds.
What is 9m/s?
A force that exists between objects that have mass.
What is gravitational force?
The equation for friction force.
What is Ff=uFN?
The friction force that is exerted on a 30kg object that is accelerating across a level surface at a rate of 2m/s2 due to a 150N applied force.
What is 90N?
An object moving at a constant speed must have zero acceleration. (True or False)
What is false?
The displacement of an object that starts at a velocity of 4m/s, then accelerates at a rate of 3m/s2 until reaching a velocity of 16m/s.
What is 40m?
A force that exists between charged particles due to their motion.
What is magnetic force?
The equation for gravitational force between any two objects.
What is Fg=(Gm1m2)/(r2)
The minimum coefficient of static friction required to prevent a 4kg mass from moving due to a 9N applied force.
What is 0.23?
Two equal and opposite forces exerted by two different objects on each other.
What is an action reaction force pair?
What is a Newton's Third Law pair?
The amount of time it takes for a rock thrown upward at 4m/s from the top of a 5m tall platform to hit the ground.
What is 1.5 seconds?
