Newton's 3rd Law: When a student on a skateboarder applies a force of 20 Newton to 'push' the ball in a positive direction, what does the student experience?
A positive (+) force of the same magnitude
A negative (-) force of equal magnitude
No force at all, only the ball experiences the force
A force that is smaller than the 'push' do to being more massive
Newton's 3rd Law: When a student (40 kg) on a skateboard applies a force to accelerate a medicine ball (5kg) to the right, the force acting on the student is:
A much smaller force
A much larger force
Exactly the same force applied to the ball
No answer is correct
The momentum of an object depends upon the object's ___________&_____________.
size and shape
mass and veloctiy
mass and energy
You have THREE different objects with different masses traveling at different velocities. Which has the greatest momentum?
Object A: really massive traveling slowly
Object B: low mass traveling really fast
Object C: a medium mass traveling at a medium speed
Object A has the greatest momentum
Object B has the greatest momentum
Object C has the greatest momentum
We cannot say which one has the most momentum without knowing the mass and velocity
Two billiard balls collide. Identify the type of collision.
elastic
perfectly elastic
inelastic
perfectly inelastic
In a two-body collision,
momentum is always conserved
kinetic energy is always conserved
neither momentum nor kinetic energy is conserved
both momentum and kinetic energy are always conserved
The law of conservation of momentum states that
the total initial momentum of all objects interacting with one another usually equals the total final momentum
the total initial momentum of all objects interacting with one another does not equal the total final momentum
the total momentum of all objects interacting with one another is zero
the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects
The law of conservation of momentum states that the total momentum of all objects interacting with each other will ________________________ no matter of the nature of the forces between the object.
increase
decrease
remain constant
fluctuate
A rock freefalls off of a cliff toward Earth. The momentum of the falling rock is _______ on its fall.
Decreasing
Increasing
Staying constant
No idea whatsoever
Which of the following has the MOST momentum?
rolling ping-pong ball
rolling bowling ball
rolling soccer ball
rolling tennis ball
Which of these has the most potential energy.
A
B
C
D
Which type of energy has to do with objects in motion?
Potential
Kinetic
As potential energy decreases kinetic energy
(a)
Which of the following is true about work?
It measures how quickly an object accelerates
It measures how much effort is applied over a distance.
It measures the change of an object's rate of speed.
It measures how much time it takes to move an object.
