What does force equal according to Newton's second law?
Mass times acceleration
Acceleration divided by mass
Mass divided by acceleration
Acceleration minus mass

It will remain constant
It will decrease
It will become zero
It will increase
Which units could be used to express a measure of force?

Meter per second squared (m/s²)
Joules (J)
Newton (N)
What would happen to an object if the forces applied on it are balanced?
It decelerates
It moves in a random direction
It accelerates
It stays at rest or continues at a constant velocity

Friction
Momentum
Gravity
Inertia
3. If a car suddenly brakes, why do passengers lurch forward?
Because of the car's speed
Because of friction
