Effects of force
Pushing a cart that is not moving is an example of ?
To move a stationary object
A school bus driving down the street is an example of what type of friction
Rolling friciton
What is the difference between speed and velocity
Speed is how far something traveled in a matter of time. Velocity is speed with a particular direction
What is potential energy
energy that is stored- simple terms energy that is standing still waiting to be used
True
Hitting the breaks on your bike
Slow down or stop a moving object
Tony pushing a car but it is not moving is an example of
Static friction
Write an example for velocity
Jenny is traveling 45mph southeast
What is kinetic energy
Form of energy that an object has due to motion
Define mass
the amount of matter that is in an object
Please write an example for change the direction of motion
Kicking a soccer ball the opposite way
Benny pushes his little sister down the slide is an example of
Sliding friction
Driving 60mph north and staying at that speed and direction is an example of what
Constant Velocity
How can you increase or decrease potential energy and give an example
changing size, shape, mass, or position
Please explain how the amount of mass something has will affect the force needed to move it
The more mass the more force needed
When I cut up an apple I am
Changing the size or shape
Benny pushes his sister on the swing
Fluid Friction
Riding a bike 10mph and increasing your velocity random amounts at random times is an example of what
Variable Acceleration
How can you increase or decrease kinetic energy and give an example
increase or decrease speed or decrease or increase potential energy
An event or process that leads to a result or change is what
The cause
Please create an example for change the speed of a moving object
Hitting the gas pedal or hitting the brakes but not coming to a complete stop
True or False
Static friction is the weakest friction and rolling is the strongest friction
Please write an example for constant acceleration
Mike running at 5mph and every 30seconds increasing his speed by 1.5mph
Write a sentence on how potential and kinetic energy are related
Potential energy and kinetic energy are related because the more potential energy has the more kinetic energy it will have
A result or change that happens because of an event or process
An effect
