100
This is the equation for average velocity.
What is v(avg)=change in displacement/change in time?
100
Give an example of projectile motion. (Physical example)
What is a thrown ball, kicked ball, etc.?
100
This is the cause of an acceleration.
What is a force?
100
This is the common formula for work.
What is W=Fd?
100
The impulse experienced by a body is equivalent to a body's change in this.
What is momentum?
200
This is the rate of change of velocity.
What is acceleration?
200
This is the path of a projectile (in the absence of friction).
What is a parabola?
200
This law states that F=ma.
What is Newton's 2nd Law?
200
This is the type of energy that is associated with an object in motion.
What is kinetic energy?
200
True or False: In a two-body collision momentum and kinetic energy are always conserved.
What is False. Momentum is always conserved, kinetic energy is only conserved in elastic collisions.
300
A feather or a metal bolt - this is the object that will hit the ground first if dropped from the same height in a vacuum.
What is neither? They would hit the ground at the same time.
300
The horizontal and vertical components of a projectile's velocity are __________ of one another.
What is independent?
300
This is the tendency of an object to maintain its state of motion.
What is inertia?
300
A construction worker pushes a wheelbarrow 5.0 m with a horizontal force of 50.0 N. How much work is done by the worker on the wheelbarrow?
What is 250J?
300
This law states that the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.
What is the law of conservation of momentum?
400
This is a physical quantity that has both magnitude and direction.
What is a vector?
400
Sam throws a ball to his friend 10 meters away. This is the point where the vertical component of the ball's velocity is zero.
What is the top?
400
A net force of 6.8 N accelerates a 31 kg scooter across a level parking lot. What is the magnitude of the scooter's acceleration?
What is 0.22 m/s^2?
400
This is the equation that expresses the work-kinetic energy theorem.
What is W=change in KE?
400
In this type of collision, two objects move separately after the collision and bother the total momentume and total kinetic energy remain constant.
What is elastic?
500
Jill and Jose take a 20.0 minute walk eastward along a straight road to a store 2.4 km away. This is their average velocity in m/s.
What is 2.0 m/s?
500
A model rocket flies horizontally of the edge off a cliff at a velocity of 50.0 m/s. If the canyon below is 100.0 m deep, what is the horizontal velocity of the rocket just before it hits the ground?
What is 50.0 m/s?
500
A hammer drives a nail into a piece of wood. Identify an action-reaction pair.
What is hammer on nail and nail on hammer; nail on wood and wood on nail.
500
What is the kinetic energy of an automobile with a mass of 1250 kg traveling at a speed of 11 m/s?
What is 76,000 J?
500
A player at first base catches a throw traveling 22 m/s. The baseball, which has a mass of 0.21 kg, comes to a complete stop in the glove after 0.15 s. Assuming the force of the glove was uniform, what force did the glove exert on the ball?
What is -31N? (or 31 N in the opposite direction of the throw).
