Speed, Velocity, & Acceleration
This is the unit used to measure acceleration.
What is m/s^2 or m/s/s?
This is the rate of acceleration due to gravity on planet earth.
What is 9.8 m/s/s?
This is a statement of Newton's 3rd law.
What is 'for every action there is an equal and opposite reaction'?
Projectiles follow a trajectory in this shape.
What is a negative parabola?
This is a value with magnitude and direction.
What is a vector?
This is the difference between speed and velocity.
What is speed is a scalar and velocity is a vector?
This is the weight of a 19 kg object on earth.
What is 186.2 N?
This is a statement of Newton's 1st law.
What is 'an object in motion tends to stay in motion and an object at rest tends to stay at rest, unless acted upon by an outside force'?
These are the two main parameters for projectile motion.
What are initial velocity and angle of force applied?
This is the shortest length between two points.
What is displacement?
This is the average velocity of a car that covers 150 m in 90 minutes (in km/hr).
What is 100 km/hr?
This is the velocity of an object in free fall after 2.1 seconds.
What is 20.6 m/s?
This is the momentum of a 9 kg obect moving at 7 m/s.
What is 63 kgm/s?
What is 25 meters?
This is the position that is chosen as the origin or staring point in motion.
What is a reference point?
This is the acceleration of an object that goes from moving at 6 m/s to 2 m/s in 0.4 seconds.
What is -10 m/s^2?
This is the point in free fall where the drag force has equaled the weight force.
What is terminal velocity?
This is the force of a 7 kg object accelerating at 8 m/s/s?
What is 56 N?
This is the total velocity of a projectile launched with a velocity of 19 m/s at 45 degrees after 0.75 seconds?
What is 14.8 m/s?
This is the sum of the coordinate vectors (3,-2) and (4,5).
What is (7,3)?
How can you get velocity and acceleration from a graph of position vs time?
Velocity is the slope of the PvT graph, Acceleration is the slope of the VvT graph.
This is the gravitational attraction between a 1.4x10^9 kg object and a 2.7x10^5 kg object if their midpoints at 185 m apart.
What is 0.74 N?
This is a free body diagram of an object with a mass of 1.4 kg resting on a table with the weight and normal force labeled.
{drawing}
This is the total displacement of a projectile launched at 22 m/s at 52 degrees after 0.25 seconds.
What is 13.6 meters?
This is the magnitude form of the coordinate vector (6,2).
What is (6.3, 18.4 degrees)?
