if an object stays still or continues moving at the same speed and in the same direction, it is a _______ force.
weak
strong
balanced
unbalanced
What is Newton's 2nd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
What is Newton's 3rd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
What explains a quantity that has BOTH speed and direction?
Inertia
Force
Speed
Velocity
The reason a boat bounces off the dock when it hits it.
The boat and the dock repel each other.
When the boat exerts a force on the dock, the dock exerts a force on the boat.
If an object is accelerating, then the forces acting on it must be:
Balanced
Unbalanced
