The speed boats speed increased from 0m/s to 24m/s in a time span of 12 seconds. What is the acceleration?
Inertia can be described as "the tendency of an object to resist change in its motion."
True
False
What is Newton's 2nd Law?
Mass = force * acceleration
Force = mass * acceleration

The sum of all forces acting on an object and direction is called the
Balanced Force
Net Force
Unbalanced Force
Contact Force
The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:
Normal Force
Gravitational Force
Friction Force
Air resistance
What is the definition of a force?
Net force equal 0N and there is no change in the object's motion
the overall force acting on an object after all forces are combined
a push or a pull that acts on an object
The force does not equal 0N, the object accelerates
