Which law? A large crate is placed on the flatbed of a truck but is not tied down. As the truck accelerates forward, the crate slides across the bed until it falls out .
a) 1st Law
b) 2nd Law

A large crate is placed on the flatbed of a truck but is not tied down. As the truck accelerates forward, the crate slides across the bed until it falls out . Why?
a) The box is resisting acceleration due to its inertia.
b) The box is accelerating with the truck.
c) The box has an unbalanced force acting on it.
d) The box exerts a force on the truck bed which pushes back on the box with equal force.

A mammoth is moving east at a constant speed of 4.44 m/s in the presence of friction effects. What is the net force on the mammoth?
a) Less than zero
b) Greater than Zero
c) Zero
d) There are no forces acting on the mammoth

Sarah and Teyonce face each other holding separate force scales. The scales are hooked together and slowly they both begin pulling on them. Compare the scale readings:
a) Teyonce's scale has a greater reading
b) Sarah's scale has a greater reading
c) there is no way to know which scale has a greater reading
d) both scales have the same reading

a) 1st Law
b) 2nd Law
c) 3rd Law
d) 4th Law
