A leftward force is applied to a crate to push it across the floor at a constant speed. Which is the correct force diagram?
A hockey puck glides to the right across the ice at a constant speed. What would the force diagram for this look like?
The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:
normal
gravity
friction
applied force
When determining the NET force on an object you should (TWO correct answers):
subtract forces in opposite directions
add forces in the same direction
subtract forces in the same direction
add forces in the opposite direction
multiply the forces in the same direction

Which object would fall with greater acceleration in a vacuum - leaf or pebble?
The leaf
The pebble
Difficult to determine without more information
Both accelerate at the same rate

9.81 m/s2
0.0 m/s2
9.81 m/s

If air resistance is ignored, objects of different masses when dropped from rest
fall with equal accelerations and with equal displacements
fall with equal accelerations and with different displacements
fall with different accelerations and with different displacements
fall with different accelerations and with equal displacements
A hammer is dropped on Earth and the Moon. If gravitational pull on the Moon is about six times weaker than on Earth, where does a hammer fall faster?
Moon
Earth
No difference
Depends on the mass of the hammer
The state that exists when the only force acting on an object is gravity is called
momentum
acceleration
inertia
free fall
The standard acceleration due to gravity (or standard acceleration of free fall), is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:
9.8 m/s.
9.8 m.
9.8 m/s2.
9.8 s.
What happens to the velocity of a ball as it is dropped off a cliff?
It decreases at a uniform rate
It increases at a uniform rate
It is constant
It increases at a non-uniform rate
