Momentum Conceptual
Momentum in a system is conserved as long as this is not acting on the object.
What is an outside force?
This is the definition of impulse.
What is change in momentum?
An egg of mass 0.02 kg is travelling at 10 m/s. What is the egg's momentum?
0.2 kg*m/s
This is the location of a uniformly dense object's center of mass.
What is the center of the object?
This is the acceleration of an object in freefall.
What is 9.8 m/s^2?
The momentum of an object can be increase if this is increased.
What is velocity/mass?
This is the unit of impulse.
What is kg*m/s?
A 10 kg toy car is travelling at 3 m/s. The car then accelerates to 7.5 m/s. What is the magnitude of the impulse experienced by the car?
45 kg*m/s
This is the definition of center of mass.
What is the average position of an object?
This is the type of energy an object has when it is above the ground.
This is the unit of momentum.
What is kg*m/s
When given a graph of force during a collision over time, this is how you find the impulse experienced.
What is the area under the curve?
A 2 kg ball of clay is thrown at a wall at 4 m/s. The ball hits the wall and comes to a complete stop after 0.002 seconds. How much force did the wall apply to the ball of clay?
4000 N
The velocity of the center of mass does not change unless acted upon by this.
What is an outside force?
This is the mathematical symbol used to represent coefficient of friction.
What is mu?
This is how Isaac Newton originally defined momentum.
What is an object's quantity of motion?
What is force?
A 1.5 kg block traveling at 3 m/s hits a stationary block of 2 kg. What is the velocity of the blocks after they collide and stick together?
1.28 m/s
Two objects lie about a meter apart. Object A has a mass of M and object B has a mass of 2M. The center of mass is closer to this object.
What is object B?
This is the concept that the amount of energy in a system doesn't change unless acted upon by an outside force.
What is conservation of energy?
Energy is conserved in this type of collision.
What is elastic?
A clay ball is thrown at the ground. At the same time, a bouncy ball of the same mass is thrown at the ground as well. This is the object that will experience a greater impulse.
What is the bouncy ball?
Two bumper cars of 40 kg are moving towards each other. Car A is traveling at 3 m/s and Car B is travelling at -2.3 m/s. After the collision, Car A is travelling at -0.45 m/s. What is the final speed of Car B? What type of collision is this?
1.15 m/s. Inelastic.
Two carts, one of mass M and one of mass 2M are stationary on a track. A spring extends, pushing the two carts away from each other. This is the direction the center of mass will move in after the explosion.
What is it won't move?
This is the name and value of G in the equation:
Fg = G*m1*m2/r^2
What is the universal gravitational constant?
G = 6.67x10^-11
