The length of the force vector is proportional to what property of a force?
Why is force not a scalar qusntity?
What happens to an object in motion when it experiences a nonzero net external force?
Why does it require much less force to accelerate a low-mass object than it does to accelerate a high-mass object the same amount?
How do mass and weight vary with altitude?
Distinguish between mass and weight
How does the force of static friction on a crate you cannot budge compare to the force you exert on it?
Assume that the crate is on a flat surface.

The length of the force vector is proportional to what property of a force?
The magnitude of the force.
Why is force not a scalar quantity?
Since force has both the magnitude and direction.
What happens to an object in motion when it experiences a nonzero net external force?
acceleration.
Why does it require much less force to accelerate a low-mass object than it does to accelerate a high-mass object the same amount?
Newton's law
How do mass and weight vary with altitude?
the high the altitude, the lower the weight. But the mass does not change.
Distinguish between mass and weight
weight is a force. As I said above, weight would depends on the altitude but mass does not.
How does the force of static friction on a crate you cannot budge compare to the force you exert on it?
Assume that the crate is on a flat surface.
If the force I exert on the crate is greater than the force of static friction on the crate, the crate will start acceleration. Otherwise, the crate would not move.
