Kinematics in 1D
This physical quantity describes how fast an object’s position changes with time and includes direction.
Velocity
This term is used for any object moving in more than 1 dimensions.
Projectile
According to Newton’s Second Law, the net force on an object equals the product of what two quantities?
Mass and Acceleration
Displacement, velocity, and acceleration are all types of what kind of quantity? Hint, this involves how much there is and where it is pointed towards to.
Vectors
What is the path traveled by a projectile called?
Trajectory
This quantity is defined as the product of mass and velocity.
Momentum
On a velocity–time graph, the slope at any point represents this quantity.
Acceleration
An object moves with constant speed but changing direction. Its acceleration is not zero because of this reason.
Velocity is changing
This force prevents an object from passing through a surface and acts perpendicular to that surface.
Normal Force
What kind, and how much, is the acceleration experienced by free falling objects?
Acceleration due to gravity, -9.8 m/s2
Relative to the total time, how much time is taken by a moving projectile to reach its maximum height?
Half of the total time of flight
This law states that for every action force, there is an equal and opposite reaction force.
Newton's Third Law of Motion
A ball is thrown straight upward. At the highest point of its motion, ________ is zero while __________ is not zero.
Velocity is zero and acceleration is nonzero
When acceleration is constant, this kinematic equation relates displacement, initial velocity, time, and acceleration:
d = v0t + 1/2 gt2
The law states that the change in ______, which for a moving object, is its product of mass and velocity, is equal to _______, which is the product of force applied and change in time.
