Forces
A force is a?
Push or a Pull
Motion always begins or ends with this.
A Force
For every force.
There is an equal and opposite force.
Velocity is associated with a specific direction while speed is not.
If an object is traveling at sixty miles per hour how far will it travel in an hour.
60 miles
This is the force which pulls on all things with mass from a distance.
Gravity
Changes in motion can only occur when one of these is applied to an object.
An Unbalanced Force
A ten pound ball traveling at thirty m/s runs into a one pound ball which is stationary. What is the relationship between the forces applied to each of them.
They are equal and opposite.
Acceleration is the measurement of this.
The change in the velocity of an object.
If an object travels 30 miles in ten minutes how fast is it traveling.
120 mph
This is the kind of force which results from to objects touching one another.
Contact Force
Horizontal motion can only be caused by this?
A force applied horizontally.
An object in motion will.
continue traveling in a straight line at a constant speed unless an outside force is applied.
Equilibrium is when this is true about an object.
All applied forces are balanced.
10,000 grams is how many newtons?
100 Newtons
This is the force which makes it more difficult to push something across concrete than ice.
Friction
An object rolling across a frictionless surface will?
Continue rolling at a constant speed unless an outside force is applied.
Why does a child go flying off of their sled when it collides with a pile of snow at the bottom of the hill.
Inertia
The net force applied to an object is equal to this.
The sum of all forces applied to an object.
What is one half of three quarters.
three eighths
This is the force which makes it difficult to start moving a heavy object.
Static Friction
Why does a basketball shot travel in an arc?
Only its vertical motion is affected by gravity, while its horizontal motion has only very small counteractive forces.
An object in equilibrium will do one of these two things.
Remain Motionless, or Continue to move in a straight line at a constant speed.
When an object applies a force to another object this is called an.
Interaction
If an object with a mass of 10kg is accelerating at a rate of 9.81 m/s squared how many newtons is the force it will create on impact with another object.
98.1 Newtons
