Motion 1
The change in the position of an object is known as this.
Displacement
What is a car doing if on a velocity-time graph it is a straight line down?
slowing down
What type of speed is calculated using a certain distance over a given period of time?
Average speed
If a car is travelling 5 km and it takes them 1 hour, what is the speed of the car?
5 km/hr
Motion of a car if the line on the distance-time graph is horizontal.
Not moving
Acceleration that does not change in time is called this.
Constant acceleration
The starting point you choose to describe the location, or position, of an object.
reference point
What units are used for acceleration?
m/s2
The slope of a velocity vs. time represents this.
acceleration
The metric units for distance and displacement
meter
The amount an object moves is known as this.
Distance
Stopping distance = ? + ?
Reaction distance + braking distance
This is where an object is located
position
The rate of change in velocity is known as this.
average acceleration
Acceleration is calculated using this equation.
change in velocity over time

Velocity
What is its speed if a car travels 300 meters in 20 seconds?
15m/s
What are the differences between a vector and a scalar quantities?
Vectors have a DIRECTION
What units are used to measure Force?
Newtons
The distance an object moves in a unit of time.
Speed
The magnitude of an object’s motion with no regard to direction is this.

Displacement
The velocity of an object at any given time is known as this.
instantaneous velocity
When looking at a graph the steepness of a line is known as the _______
Gradient
What are three ways an object can accelerate?
speed up, slows down, or change direction
