Net force is the sum of all forces acting on an object.
An object with balanced forces acting on it will accelerate.
The resultant vector represents the total effect of two or more vectors.
The slope of a distance vs. time graph represents speed/velocity.
A constant velocity means both speed and direction remain unchanged.
Acceleration can only occur when an object speeds up.
If two forces act in opposite directions, the net force is found by adding them.
A time vs. distance graph with a straight horizontal line indicates the object is at rest.
A vector includes both magnitude and direction.
A velocity vs time graph can't have a negative velocity.
What is the unit of force?
Two forces, 10 N and 5 N, act in the same direction. What is the net force?
A car is moving at 20 m/s and comes to a stop in 4 seconds. What is its acceleration?
Which of the following represents a vector quantity?
On a time vs. distance graph, what does a steeper slope indicate?
Which of the following scenarios involves no acceleration?
What happens when forces on an object are unbalanced?
A vector is described as having:
The slope of a velocity vs. time graph gives:
A horizontal line on a velocity vs time graph shows:
To describe motion, you need a
An object moving in a straight line at constant speed has
To find how long an object was in motion, you would divide the distance by the
