Kinematics Vocabulary
This term describes how fast an object moves and is calculated by distance traveled by the time taken.
What is speed?
Because it includes both how fast an object travels and how the specific path direction it takes, velocity belongs to this class of quantities.
What is a vector quantity?
A remote-controlled car travels a total distance of 150 meters in exactly 12 seconds. This is the average speed of the car.
What is 12.5 m/s?
A car's velocity increases from 5.0 m/s to 30 m/s in 3.0 s. This is the cars acceleration.
What is 9 meters per second squared?
A motorcycle rider applies brakes and slows down uniformly from 30 meters per second to 10 meters per second over a duration of 4 seconds. This is the magnitude (change in v) of the motorcycle's deceleration.
What is 5 meters per second squared?
This term refers to the continuous progression of events or the duration over which an object's motion occurs.
What is time?
The rate of change of velocity over time.
What is acceleration?
A drone flies at a constant speed of 12 meters per second for a duration of 30 seconds. This is the total distance the drone covers.
What is 360 meters?
A rocket launch vehicle fires its main boosters from rest at a constant acceleration rate of 15 meters per second squared for 6 seconds. This is the final velocity of the vehicle at the end of the burn.
What is 90 meters per second?
A passenger train is decelerating at a rate if 2 meters per second squared, taking 15 seconds to come to a stop. This was the initial velocity of the train before the brakes were applied.
What is 30 meters per second?
This type of physical quantity is completely described by its magnitude or size alone, without any regard to direction.
What is a scalar quantity?
The rate of change of position; distance traveled per unit time (no direction)
What is speed?
A cyclist riding at a steady speed of 8 meters per second needs to cover a linear distance of 400 meters. This is the total time required for the trip.
What is 50 seconds?
A sprinter starts from a standstill and reaches a top velocity of 9.5 meters per second in a time frame of 2 seconds. This is the sprinter's average acceleration rate.
What is 4.75 meters per second squared?
A car accelerates from rest to 3.0 meters per second squared for 5 seconds. This is how far it travels.
What is 15 meters?
This type of physical activity requires both a numerical magnitude and a specific directional component to be fully defined.
What is a vector quantity?
Measurements like a mass of 50 kg, a temperature of 22 degrees Celsius and duration of 10 seconds belong to this class of quantities.
What are scalar quantities?
A skateboarder travels 12 meters in 3 seconds, stops completely for 2 seconds to reset, and then travels another 18 meters in 5 seconds. This is their average speed for the entire 10-second timeline.
What is 3 meters per second?
A driver steps on the gas pedal, causing the vehicle's velocity to change from 10 meters per second to 28 meters per second over a span of 3 seconds. This is the acceleration of the vehicle.
What is 6 meters per second squared?
Calculate the velocity of a car that travels 556 km northeast in 3.4 hours
What is 16.3 km/h
This vector quantity measures the straight-line distance and overall direction from an object's initial starting position to its final position.
What is displacement?
The shortest straight-line distance from starting point to ending point, including direction
What is velocity?
A cyclist travels 7,600m at a constant speed of 4.0 meters/second. How much time (in minutes) does the ride take?
What is 31.7 or 32 minutes?
A skateboarder starts from rest and accelerates at 1.8 m/s/s for 6 seconds. This is the skateboarders final velocity.
What is 10.8 m/s?
An RC quadcopter flies 120 meters due north, turns, and flies another 40 meters due north, taking a total flight time of 20 seconds. This is the magnitude of the quadcopter's average velocity.
What is 8 meters per second?
