Position (Be able to give me examples)
Where an object is located
What is the formula for time?
t = d/s
Mass
A measure of the amount of matter in an object; measured in grams
7 m/s
average speed of a skateboarder travelling 840m in 120 seconds
Constant Speed, Getting Further Away
What is this graph showing?
Direction
the path that an object is moving or facing
Friction
A force that opposes motion between two surfaces that are in contact
Newton's Second Law
Force = mass x acceleration
Distance (Be able to give me examples)
The measurement from one place to another.
velocity
speed and direction
What is the formula for distance?
d = s x t
Force
A push or pull exerted on an object
Acceleration (Be able to give me examples)
A change in an object's velocity or direction. (Ex: Final Velocity - Beginning Velocity / time)
decreasing speed
What is this graph showing?
Distance
How far an object moves.
s = d/t
average speed
Increasing accelerating
Object is at rest, no motion
Newton's First Law
An object in motion stays in motion & an object at rest stays at rest unless acted upon by an unbalanced force
constant speed
The rate of change of position in which the same distance is traveled each second
A group of friends hiked 12 kilometers west in 2 hours. What was the group's velocity?
6 km/hr west
potential energy
stored energy; energy of position
kinetic energy
energy of motion
Constant speed
Standing Still-not moving
50km/h
average speed of a truck travelling 400km in 8 hours
Direction (Be able to give me examples)
The path that an object is moving or facing. (Ex: N, E, S, W)
kinetic energy
the energy an object has due to its motion
0.75 km/h
average speed of a tram travelling 15 km in 20 hours
1- Constant Speed 2-Acceleration 3-Stopped 4-Deceleration
What is this graph 1-4 Showing?
Increasing Speed and Getting Further Away
What is this graph showing?
Balanced force
Forces acting on an object that combine and form a net force of zero
60m/s
average speed of a sprinter running 150 in 2.5 seconds
Unbalanced force
two or more forces that are not equal and opposite of one another; can cause change in motion
Net force
The combination of all the forces acting on an object
Decreasing speed
acceleration
change in speed or direction; change in velocity; slowing down, speeding up, turning
speed
measure of the distance an object travels per unit of time
3 ways velocity can change
The speed of an object changes The direction of an object changes When both the speed and direction change
A car travels 120 miles in 3 hours. What is the car's speed?
40 miles/hour
average speed
The total distance traveled divided by the total time taken to travel that distance
Newton's Third Law
For every action there is an equal and opposite reaction
60km/h
average speed of a car travelling 210 km in 3.5 hours
speed formula
speed = distance/time
What is the speed of a car that travels 600m in 60 seconds?
10 m/s
Potential Energy
stored energy that results from the position or shape of an object
Newton
Unit for Force
Acceleration
What is this graph showing?
Inertia
The tendency of an object to resist a change in motion; (Newton's 1st Law - The Law of ________)
Motion (Be able to give me examples)
A change in an object's position, direction or location
