To find the speed of an object in motion, you need to measure
time and velocity
distance and time
distance and direction
time and direction
Which of the following can be measured by a vector?
velocity
position
distance
speed
The change in velocity over time is called acceleration.
True
False
To calculate the acceleration, you need to know both the final velocity and the initial velocity of an object.
True
False
If you push or pull a moving object,
it will not accelerate
its motion will change
its mass will change
its velocity will remain the same
_______________________________ is the change in position over time.

Newton's First Law
motion
net force
force
inertia
The overall force acting on an object when all forces are combined is called
inertia

The mathematical relationship between momentum, mass, and velocity is
momentum = velocity/mass
momentum = mass/velocity
momentum = mass x velocity
velocity = momentum + mass
If momentum is conserved, then the total momentum after a collision is equal to
the momentum of the faster object
the momentum of the more massive object
the total momentum before the collision
the total force before the collision
Which of the following best show the mathematical relationship between force, mass, and acceleration.
