Left-Right; Up-Down
any kind of change in an object’s position as observed from a basic reference point
motion
what do you call the path a projectile travels upon launch?
trajectory
called "mass in motion"; this quantity describes how fast a specific massive quantity is moving
momentum
Two objects thrown into contact with each other resulting to an exchange in properties
Collision
a propagating dynamic disturbance that travel between vibrating and oscillating fields.
Wave
the branch of physics which deals with the study of motion without concern for the surrounding forces that cause it
Kinematics
At which angle should you launch a projectile to get the greatest range?
450
between two cars of the same mass and varying speeds, which car would have greater momentum?
the faster car
these collisions are ideal and simulative, wherein objects still have different final velocities after colliding
Elastic Collisions
these waves travel at a direction perpendicular to the material action/force
Transverse
how many kinematic equations are there in general?
when launched along the ground, how would you describe the velocity of an object at the x-axis?
it moves at a constant velocity
A martial artist hits the board with 264.25 N of force. If the board is hit within three-fourths of a second, how much impulse is imparted on it?
I = 198.19 N s
why do inelastic collisions have the same final velocity after colliding?
the objects tend to stick together after the crash
Light can travel through solids, liquids, and gases. They can also propagate when all three are not present
Electromagnetic
A ball is thrown horizontally with an initial velocity of 9.75 m/s off the top of a tower 12.50 seconds ago.
What is the ball’s horizontal velocity?
vx = 9.75 m/s
as an object is launched above the ground, how would you describe its acceleration along the y-axis?
its acceleration in the y-axis is constant at 9.81 m/s2
A 5.25-kg wheel tire rolled along a track at a velocity of 16.75 m/s. How much momentum does the tire have?
p = 87.94 kg x m/s
the sum of the momenta of two objects after a collision is equal to their sum after; according to what law?
The Law of Conservation of Momentum
All waves have five properties. Give four of them.
Wavelength, Frequency, Period, Energy, Amplitude
A ball is thrown horizontally with an initial velocity of 9.75 m/s off the top of a tower 12.50 seconds ago.
What is the ball’s vertical velocity?
vy = 122.63 m/s
◦Two paper planes were thrown at different angles, with one flying at 19.020. At what angle did the other plane fly at if both landed at the same place?
70.980
prove that:
I = Ft = Δp

A 70 kg car moving at 15 m/s hits a 40 kg motorcycle moving at 24 m/s in the opposite direction. What would be the final velocity of the car if the motorcycle stopped upon impact?
28.71 m/s
A 50 meter-long wave moves at a speed of 2.50 m/s. What is the wave's frequency?
0.05 Hz
