A car is travelling along the highway at a speed of 30 m/s (about 70 miles/hour). The car has a mass of 1200 kg, and the coefficient of friction between the tires and the road is 0.62. The driver sees a tree fall on the road in the distance. The driver immediately slams on the breaks.
Apr 8, 2019 · Reason: Newton’s first law does not state that there can be no forces acting on an object moving with constant velocity—only that the sum of the forces must be zero (sometimes worded as “no unbalanced forces”).
How do balanced and unbalanced forces affect an object's motion? Inertia is the resistance of any physical object to any change in its state of motion, including

Jul 2, 2024 · Unbalanced forces mean that the forces have combined in such a way that they do not cancel out completely and there is a resultant force on the object. For example, imagine two people playing a game of tug-of-war, working against each other on opposite sides of the rope.
The progression toolkit for balanced and unbalanced forces reminds students that in everyday situations there are usually several forces acting on an object at the same time. Students begin by identifying situations in which pairs of forces may or may not be balanced.
