Column 1
As a care package falls from a high-flying stationary helicopter, its velocity increases and its acceleration
How the acceleration changes when the mass of an object is increased (one increases the other decreases)
inversely proportional
If the force acting on a cart doubles, what happens to the cart's acceleration?
doubled
What would exert a small amount of pressure on the ground?
When an object gets to its top speed and is no longer able to accelerate
terminal velocity
As a care package falls from a high-flying stationary helicopter, the amount of air resistance acting on it
increases
When the acceleration of an object changes as a result of a change in force applied to it (one increases the other increases)
directly proportional
Suppose a cart is being moved by a force. If suddenly a load is dumped into the cart so that the cart's mass doubles, what happens to the cart's acceleration?
halved
A man stands on a scale with two feet, the scale reads 300N. When he lifts one foot the scale will read __________.
300 N
The force of gravity on a 10-kg object is ____________ more than on a 1-kg book
10 x
N (Newton) is the unit for ___________.
force
The formula you use to figure out the mass when you are given the force and acceleration for a situation.
m = F / a
A car weighs 600 N, when sitting at rest on the street, the net force on the car is _________.
0 N
Unit of pressure defined as newton’s per square meter
m/s^2 (meters per second per second) is the unit for _________
acceleration
kg (kilogram) is the unit for __________
mass
The formula you use to figure out the Force when you are given the acceleration and mass for a situation.
F = m x a
A particle is accelerated through space by a constant 10-N force. Suddenly the particle encounters a second force of 10-N in a direction opposite to that of the first force. The particle continues at a(n)
constant speed
Defined as the force per area
= force / area of application
Pressure
Which of these two balls if dropped would have the greater force acting on it a steel ball or tennis ball of the same diameter?
steel ball
Combination of all the forces acting on an object.
net force
The formula you use to figure out the Acceleration of an object when you are given the force and mass for a situation.
a = F / m
Accelerations are produced by
forces
What would exert a large amount of pressure on the ground?
high heel shoes
A box is dragged without acceleration in a straight-line path across a level surface by a force of 450 N. What is the frictional force between the box and the surface?
450 N
