A constant horizontal force acts on a cart on a frictionless track. The acceleration is set by Newton's second law, a = F / m: more force gives more acceleration, more mass gives less. Watch the cart speed up and read the numbers as you change the force and the mass.
MissionRun the cart, then predict what happens to the acceleration if the mass is doubled at fixed force.Streak 0Best 0
Keeping the force the same, doubling the mass changes the acceleration to:
resultant force F6.0 N
mass m2.0 kg
acceleration a = F / m3.0 m/s²
current velocity v0.0 m/s
Newton's second law: the resultant force equals mass times acceleration, F = ma.
