- Q2Use inertia to explain why you feel pressed back into the seat of a car when it accelerates.Because of your inertia, your body tends to remain in place. The car seat causes you to accelerate, therefore, by exerting force on your back.all of the aboveBecause of your gravity, your body tends to remain in place. The car seat causes you to accelerate, therefore, by exerting force on your back.Because of your inertia, your body tends to remain in place. The car seat causes you to accelerate, therefore, by exerting force on your front.30sS8FE-Ia-16
- Q3How could you keep an object's acceleration the same if the force acting on the object were doubled?all of the followingyour could tripple the object's massyour could double the object's massyour could double the object's motion30sS8FE-Ia-16
- Q4Explain why a car with a large mass might use more fuel than a car with smaller mass. Assume both cars drive the same distance.A greater force is required to accelerate a most massive car, therefore, more engine power and more fuel are needed.A greater friction is required to accelerate a more massive car, therefore, more engine power and more fuel are needed.A greater force is required to accelerate a more massive car, therefore, more engine power and more fuel are needed.A lesser force is required to accelerate a more massive car, therefore, more engine power and more fuel are needed.30sS8FE-Ia-16
