forces
(Answer with "What is...")
A push or a pull on an object resulting from the interaction with another object.
What is a force.
(Answer with "What is...")
An objects force is directly related to its mass and acceleration.
What is Newton's Second Law.
(Answer with "What is...")
Change in position measured by distance and time.
What is Motion.
(Answer with "What is...")
The rate of change in the speed of an object.
What is acceleration.
(Answer with "What is...?)
The ability to cause change.
What is energy
True or false:
The more Newtons, the less the force.
False
(Answer with "what is...")
An object will not start moving until a force is acted upon it.
What is Newton's First Law
What type of line is shown to indicate an object not moving on a distance-time graph?
A horizontal line.
What goes in the brackets?
Acceleration= Final speed-[ ] / time
Beginning speed
(Answer with "What is...?)
The support, or point of rest, on which a lever turns in moving a body.
What is a fulcrum.
(Answer with "What is...")
The sum of forces acting on an object.
What is Net force.
(Answer with 'What is...")
For every action, there is an opposite and equal reaction.
What is Newton's Thrid Law.
What line indicates constant speed on a distance-time graph.
A straight diagonal line.
(True or False?)
A positive change will show slowing down.
False.
(Answer with "What is...?)
The advantage created by a machine that enables people to do work while using less force.
What is a mechanical advantage.
True or False?
Force has size and direction.
True
True or False?
Inertia is the object's resistance to change its motion (The object must be moving).
False!
Inertia is the object's resistance to change its motion (whether it is moving or not).
On a speed-time graph, what does a straight diagonal line mean in terms of speed?
Acceleration.
(True or False?)
the units of acceleration are meters per second (m/s/s).
True
(True or False?)
Simple machines are tools that make work harder.
False.
True or False?
Friction releases heat energy.
True!
(True or False?)
Force = Mass x Speed.
False.
Force = mass x acceleration.
(True or False?)
If an object is moving at a constant speed, it means it has the same increase in distance in a given time.
True!
A skater starts off at 2 m/s. At the end of 3 seconds, the speed is 10 m/s. What is the acceleration?
2.7 m/s/s
(True or False?)
These machines allow us to use a smaller force to overcome a larger force.
True.
