1
Q
What can a resultant force do?
A
Change the speed of an object
Change the direction of motion of an object
Change both
2
Q
What is an object doing if its speed and direction of motion is changing?
A
Accelerating
3
Q
What does Newton’ s Second Law state?
A
The acceleration that the resultant force produces an object depends on the size of the resultant force and the mass (inertia) of the object
4
Q
How do you calculate force with mass and acceleration?
A
Force = mass * acceleration
