A student wants to conduct an investigation to determine if there is a relationship between the speed a cart and the cart’s kinetic energy. They should keep all variables the same except __________
the kinetic energy of the cart.
the speed of the cart.
the mass of the cart.
do none of the above.
Which has the greater effect on the kinetic energy of a moving object, doubling its mass or doubling its speed?
doubling the object’s mass
doubling the object’s speed
doubling both have equal effects
neither

continue moving at the same speed and in the same direction.
eventually slow down and stop.
What does it take to change the direction or speed of an object?
more than one force
an unbalanced force

accelerating.
in a frictionless environment.
moving with constant speed.
Imagine you were able to throw a ball in a frictionless environment without gravity. Once you let go of the ball, what will happen to the ball according to Newton’s laws of motion?
It will travel in a straight line forever.
It will travel in a straight line but eventually slow down.
It will continue to speed up forever.
It will slow down and turn.
When a person sits in a chair, they apply a force to the chair. The chair
applies a larger force to the person in the opposite direction.
applies the same size force on the person in the same direction.
applies the same size force on the person in the opposite direction.
does not apply a force to the person.
Car A and Car B are identical, but Car A is moving twice as fast as Car B. Both cars brake to a stop. Complete this sentence: The distance needed to stop Car A is ________________ the distance needed to stop Car B.

A car accelerates down the road. What is the “reaction” to the tires pushing on the road?
the air in the tires moving the car
the mass of the car pushing on the tires
the road pushing on the tires
the road moving away from the tires
How do you find the force when the mass and acceleration are given?
F= m/a
F= a/m
F= m*a
How do you find the acceleration if the mass and force are given?
A=f*m
A=f/m
A=m/f
How do you find mass if acceleration and force are given?
M=f/a
M=a/f
M=f*a
