Eric timed a race car going around a circular track for a total of 4 minutes. In order to determine the speed of the car, Eric also needs to know…
the mass of the race car.
the distance the car traveled.
the net force acting on the car.
the direction in which the car was traveling.
The force that one substance exerts on the other when they rub against each other is called

Which situation would allow the toy rocket to lift into the air?
Lift= 5 Newtons / Gravity = 5 Newtons
Lift = 3 Newtons / Gravity = 4 Newtons
Lift = 5 Newtons / Gravity = 4 Newtons
Lift = 4 Newtons / Gravity = 4 Newtons
James took 5 seconds to travel 10 meters during the scooter races. What speed was James traveling at?
.5 m/s
2 m/s

200 m/s
Newton's first law states…
when one object exerts a force on another, the second object exerts an equal force.
force equals mass times acceleration.
An object at rest will stay at rest; an object in motion will stay in motion
acceleration of the object depends on the mass.

none of the claims are true
one of the claims is true
two of the claims are true
all of the claims are true
