Question

1. match the sentences with the terms. an object tends to resist a change in motion. this force builds up when an object is pushed and explains why an object comes to a stop when the pushing stops. an unbalanced force must overcome this force before the object will move. often confused with mass, this is a measure of how the force of gravity acts upon mass. construction of this model allows the engineer to test an idea for a final design. scientific principles are applied in a process to solve problems. this is the combination of forces acting on an object.

Explanation:

1. Inertia is the property of an object to resist a change in motion.
2. Friction is the force that builds - up when an object is pushed and makes it stop when the pushing stops.
3. Static friction is the force an unbalanced force must overcome for an object to move.
4. Weight is often confused with mass and is the measure of the gravitational force on mass.
5. A prototype is a model that engineers build to test an idea for a final design.
6. Engineering is the application of scientific principles to solve problems.
7. Net - force is the combination of all forces acting on an object.

Answer:

1. Inertia
2. Friction
3. Static friction
4. Weight
5. Prototype
6. Engineering
7. Net - force
