How would Lucas determine the net force on an object if all forces act in the same direction?
Add the forces together
Subtract the forces
Multiply the forces
Weigh them
Use the force, Luke!
What is the net force of this soccer ball if Frederick and Logan kick the ball at precisely the same moment? Remember that ALL forces have a magnitude (strength) measured in Newtons (N) and a direction. Include BOTH in you answer.
(a)
When the net force is NOT zero Newtons, the forces on an object are __________ and the object will accelerate in the direction of the ___________ .
balanced; weaker force
strong; combined forces
pushing; pull
unbalanced; stronger force
Newton's first law of motion states that objects in motion maintain their velocity unless ___________ .
an unbalanced force acts on them
they're on Earth
a balanced force acts on them
they truly, deep down inside want to change
Newton's third law states that whenever one object exerts a force on a second object, the second object exerts an ________ and ________ force on the first
strong; non-contact
equal; opposite
unbalanced; atomic
electric; gravitational
evil; dark side

Two forces act on a volleyball. Which of the following statements explains why the volleyball accelerates?
The net force applied to the ball is zero Newtons (N)
The ball resists one force but not the other
Newton's second law doesn't apply to round objects
The two forces are unbalanced
The combied forces of friction and gravity acting on the box are a 35N to the right. What is the least amount of force Jadain needs to exert on the box in order to put it in the truck?
(a)
Newton's second law states that force equals _______ times ______ .
time; speed
mass; acceleration
length; height
gravity; friction
What force is necessary for Isabel to accelerate a 70kg object at a rate of 4.2 m/s2? (Remember Force = mass x acceleration)
294N
18.5N
74.2N
65.8N
If there is 72N acting on an object that weighs 6kg, how fast will it accelerate?
*Remember Force = mass x acceleration
432 m/s2
78 m/s2
None of these answers
12 m/s2
How does Newton's second law explain why the boulder will continue to accelerate to the left even if Brady applies the same force as the boulder?
Newton's second law of motion specifically states that rock beats scissors
The man is still a padawan learner and not yet strong enough in the force
Acceleration depends on an object's mass as well as force. So if the man and the boulder push with equal force, the boulder will accelerate because it has more mass
For every force there is an unequal an directional force from another random force.
