The diagram shows two forces acting on a moving train. Make a true statement about what will happen when the two forces are applied to the train
The train will come to a complete stop
The train will accelerate because of unbalanced forces.
The train will slow down because the forces are balanced.
The train will continue to move at a constant speed
Oops!
Okay!
What's the difference between speed and velocity?
Velocity is speed with direction

Okay!
Unbalanced forces cause...
Acceleration

Why does the water keep moving when the man and cup are stopped due to tripping?
Inertia (Objects in motion stay in motion, Newton's 1st Law)
Oops!

Which option correctly pairs the motion with the units?
S=m, V=m/s , A=m/s East
S=m/s, V=m/s East, A=m/s^2 East
S=m/s East, V=m/s, A=m/s^2 East
S=m/s^2 East, V=m/s East, A=m/s
