If a child is pushing a car at a constant speed, then the forces acting on the car are
What is balanced?
The formula associated with N2L
What is F=ma?
When the girl applies force to push off the wall, amount of force exerted by the wall on her is
What is equal/the same?
What is friction?
In a free body diagram, this characteristic of an arrow indicates the size of a force
What is length?
If an object is accelerating or deaccelerating, the forces acting on it can be described as...
What is unbalanced?
An object has a mass of 100kg and an acceleration of 10m/s2. The value of the force on the object is equal to this number.
What is 1000N?
In the photo, the jetpack pushes water downward, causing the user to move in this direction
What is upwards?
The force exerted by a surface on an object that prevents it from falling through
What is normal force?
In this FBD, the speed of the object is
What is changing?
A requirement to change the motion of an object
What is unbalanced force?
Four objects have equal mass, yet they all have different accelerations. The object experiencing the smallest force also has the smallest...
What is acceleration?
A man pushes on a wall with a force of 250N. The force exerted by the wall on the man has this value.
What is 250N?
This force does not exist in space.
What is air resistance?
The speed of the object in this FBD must be
What is constant?
The tendency of an object to resist a change in its motion is referred to as this.
What is inertia?
Two carts of unequal masses begin at rest, are rolled across a table, and reach the other end at the same time. Cart X has twice the mass as Cart Y. This cart experiences a greater force.
What is Cart X?
Kenny winds up his yo-yo clockwise. When he lets it fall back down, this is the direction that the string will unwind.
What is counterclockwise?
This force can be generated by stretching a rope, string, cable, etc.
What is tension?
The object in the FBD experiences a net force in this direction.
What is left?
An object in motion that is experiencing no friction would continue to move for this length of time.
What is forever?
Two train cars are connected to each other and accelerating at a speed of 2m/s2 due to an applied force of 15,000N. Car A has 4 times the mass of car B. This is the mass of Car A:
What is 6000kg?
F=ma
15000=(4m+m)2
m=1500kg, 4m=6000kg
An equal and opposite force that opposes normal force
What is gravity?
Action-reaction pairs have these two characteristics
What are equal and opposite?
The net force in the FBD shown
What is 0N?
