Momentum
100
Forces when an object is NOT changing its motion
balanced
100
When the same force is applied to objects of different mass, the smaller mass will...
accelerate more than the larger mass
100
Weight of a 5 kg object on earth.
What is 50 N (5 kg x 9.8 m/s/s)
100
The reaction force when you place your book on the desk
the force of the desk on the book
100
How momentum is calculated
What is mass x velocity (speed & direction)
200
The tendency of an object at rest to remain at rest
What is inertia
200
The effect of applying a larger net force to objects of the same mass
What is a larger acceleration
200
Why an object's weight is less on the moon than on Earth
acceleration due to gravity (g) is less on the moon than on earth
200
The size of any reaction force
What is equal to the action force
200
Momentum divided by velocity
What is mass
300
Object with more mass
What has more inertia
300
The acceleration of an 40 kg object when a net force of 400 N is applied to it.
What is 100 m/s/s (a = F/m = 400N/40kg)
300
The acceleration of ANY falling object in the absence of air (on earth).
What is 9.8 m/s/s
300
The direction of any reaction force
What is opposite of the action force
300
The TOTAL momentum of objects before and after they collide.
What is THE SAME
400
Velocity of a falling object when air resistance balances the weight of the object
What is terminal velocity (a constant velocity)
400
mass x acceleration
What is net force
400
Would cause gravity between two objects to decrease.
move the objects furhter apart from each other.
400
Forces always occur in
What are pairs (2)
400
Momentum of a 10.0 kg object running south at 5.0 m/s
What is 50.0 kg x m/s SOUTH
500
Why a person might get whiplash during a car accident
the person's inertia
500
mass x free fall acceleration
What is weight
500
The path a thrown object takes
What is a curved path (projectile motion)
500
If obect A hits object B, then object B hits....
object A (at the same time)
500
Speed of ball 2 after it collides with ball 1. Ball 1 has a mass of 2 kg - Before it collides its speed is 40 m/s, and after it collides its speed is 20 m/s. Ball 2 has a mass of 4 kg and is initially still.
What is 10 m/s (2 kg x 40 m/s) + 0 = (2 kg x 20 m/s) + (4 kg x ??)
