acceleration =
Net Force (two formula)
Net Force (sum of forces) = F1 + F2…etc.
Net Force = Greater Force - Lesser Force
Force = mass x acceleration
How is acceleration defined in a physics context?
If an object is moving at 15 m/sec and decelerates to 5 m/sec in 2 seconds, what is its acceleration?
What would be the acceleration of an object moving at constant speed?
An object accelerates from 20 m/sec to 30 m/sec in 4 seconds. What is its acceleration?
Which of the following measures acceleration?
What defines a force in physics?
What is the net force if three forces of 10 N, 5 N, and 15 N act in the same direction?
When two equal forces act in opposite directions, what is the net force?
What happens when an object is in free fall?
If a cart that has a mass of 4 kg accelerates at 4 m/sec², what is its force?
What is the effect of increasing surface roughness on friction?
What forces commonly oppose the motion of a sliding object?
How does temperature affect frictional forces?
If two objects with different weights are dragged across the same surface, what generally happens?
What type of friction occurs when an object is moving?
If an object’s velocity is increasing, what is true about the net force acting on it?
Which situation displays balanced forces?
What happens to an object’s speed if the net force acting on it is negative?
What is the force required to stop a 10 kg cart moving at 5 m/s in a short distance?
In an experiment, if equal forces are applied in opposite directions, the result is:
What is the primary factor that determines the amount of friction between two surfaces?
An object has forces of 20 N to the right and 15 N to the left acting on it. What is the net force acting on the object?
If a boat is moving forward but encounters a current flowing backward, what occurs?
What happens when an object experiences a net force of 0 N?
