What is force?
Force is a push or pull.
100
What is motion?
Motion is a change in position over time.
100
What do simple machines do?
A machine is any device that helps people do work by changing the way work is done.
100
What is centripetal acceleration?
Centripetal acceleration is the acceleration in circular motion.
100
What is the formula of the average speed?
The formula of the average speed is distance decided by time which equals d/t=s
200
What is speed?
The speed tells you how quickly the objected changed position.
200
What is average speed?
Average speed is a way to calculate the speed of an object that may not always be moving at a constant speed.
200
What is a wheel and axle?
A wheel and axle is a simple machine that is made of a wheel connected to a smaller cylindrical object, the axle.
200
What do a decrease in the magnitude of velocity called?
A decrease in the magnitude of velocity called negatively accelerate.
200
What is the formula of the mechanical advantage?
The formula of the mechanical advantage is output force divided by the input force.
300
What is velocity?
Velocity is speed in a specific direction.
300
What is net force?
Net force is the combination of all the forces acting on an object.
300
What is a lever?
A lever is a simple machine that has a bar that pivots at a fixed point.
300
What do an increase in the magnitude of velocity called?
An increase in the magnitude of velocity is called positively acceleration.
300
How to calculate the net force?
If the forces act in a same direction you just simply add them. If the forces act in an opposite direction you subtracted the smaller force from the larger force to determined the net force.
400
What is inertia?
Inertia is the tendency of all objects to resist a change in motion.
400
What is mass?
hahahah
400
What is a pulley?
A pulley is a simple machine that has grooved wheel that holds a rope or a cable.
400
What is interval?
Interval means a period.
400
How to calculate the force?
Use mass times by acceleration equals force ,which is also written in F=ma.
500
What is acceleration?
Acceleration is the rate at which velocity changes.
500
What do acceleration depending on?
The Acceleration of an object depends on the mass of the object and the amount of force applied.
500
What is a mechanical advantage?
Mechanical advantage is the number of times the machine multiplies the input force.
500
What is acceleration change in?
Acceleration is change in velocity.
500
How to calculate the average acceleration?
The average acceleration equals (final velocity-starting velocity) divided by time.(V2-V1)/t =a.
