This term describes the motion of an object under the influence of gravity alone, with no other forces acting on it.
What is free fall?
100
This is the force that resists the motion of an object sliding or rolling across a surface.
What is friction?
100
Since momentum has both magnitude and direction it can be classified as this.
What is a vector?
100
This term describes the motion of an object moving in a circular path at a constant speed.
What is uniform circular motion
100
This principle explains why objects float or sink in a fluid, based on the displaced fluid's weight.
What is Archimedes' Principle?
200
Draw a P-t graph of an object moving at a constant velocity in a positive direction.
200
Two forces acts on an object at an angle 90o to each other. What can we use to find the resultant force?
What is the Pythagorean theorem?
200
This is the name we give for the change in momentum.
What is impulse?
200
This quantity is defined as the product of the moment of inertia and angular acceleration.
Torque
200
This principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure.
What is Bernoulli's Principle?
300
This is the velocity and acceleration of an object at the highest point of the projectile motion.
v= 0 m/s ; a =9.8 m/s2 downward
300
This is the force that resists the motion of a fluid past a solid object and is dependent on the object's speed, shape, and the viscosity of the fluid.
What is drag force?
300
This is a type of collision where Kinetic Energy is not conserved.
Inelastic collision
300
This is what happens when rotational velocity and rotational acceleration both have the same sign.
What is rotational velocity increases?

Draw a FBD for a object floating in a liquid.

This information will determine the time it takes a horizontally launched object to reach the ground from the top of a table.
What is the height of the table?

A 10 kg object is moving at a constant speed on a horizontal surface. If the coefficient of kinetic friction between the object and the surface is 0.3, calculate the applied force.
What is 30 N?
400
This is the final velocity a 500 kg car that starts at rest will have after it is rear-ended by a 650 kg that is initially going 20 m/s. The cars lock together after they hit.
What is 11.3 m/s?
400
A disk with a radius of 0.5 meters is spinning at an angular velocity of 10 radians per second. What is the linear velocity of a point on the edge of the disk?
What is 5 m/s ?

A cylindrical tank with a radius of 1 m and a height of 2 m is filled with water. Calculate the hydrostatic pressure at the bottom of the tank.
What is 20,000 Pa?
500
This is the speed and direction of a projectile launched upward at 25 m/s, 3 s into the flight.
What is 5 m/s , downward?
500
A 5 kg block is placed on a frictionless inclined plane at an angle of 30° to the horizontal. Calculate the acceleration of the block down the incline, assuming there is no friction and only gravity acts on the block.
What is 5 m/s2
500
A 5 kg loaded rifle is initially held at rest and then fired. The 0.05 kg bullet leaves the barrel at 450 m/s. This is the final momentum of the bullet-gun system.
What is zero?
500
This is the angular acceleration of a solid cylindrical disk with a mass of 8 kg and a radius of 0.2 m that initially at rest and experiences a constant torque of 4 Nm. (I = (1/2)MR²)
What is 25 rad/s2?
500
A fluid flows through a horizontal pipe with a pressure of 200 kPa and a velocity of 3 m/s. If the fluid density is 850 kg/m³, calculate the pressure at a point where the velocity increases to 5 m/s.
What is 193.2 kPa?
