What is the formula for calculating force?
Remember what F, m, and a stand for.
What unit do we use to measure force?
Think of the scientist who gave his name to this unit.
What is the Second Law of Motion?
Think about the relationship between force, mass, and acceleration.
True or False: A heavier object always accelerates faster than a lighter object when the same force is applied.
Reflect on the implications of F = ma.
A 12 kg object is pushed with a force of 36 N. What is the acceleration of the object?
Use F = ma to find the acceleration.
If a car accelerates from rest to a speed of 20 m/s in 5 seconds, what is the force acting on the car if its mass is 1,500 kg?
Remember to calculate acceleration first!
