Force and Motion Benchmark

Front

What is the dependent variable in a distance vs. time graph?

Back

The dependent variable is distance, which is graphed on the Y-axis.

Front

How does reducing friction affect the motion of an object on a ramp?

Back

Reducing friction will cause the object to speed up as there is less resistance to its motion.

Front

Which material would be best for a warehouse floor if workers need to push heavy boxes?

Back

The best material would be tile, as it has the least friction, allowing boxes to slide more easily.

Front

What forces are typically acting on a car in motion?

Back

Forces acting on a car include gravity, friction, and applied forces from the engine.

Front

What is a fair test in an experimental investigation?

Back

A fair test is one where only one variable is manipulated at a time to ensure accurate results.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, slowing down or stopping moving objects.

Front

What is the difference between independent and dependent variables in an experiment?

Back

The independent variable is the one that is changed or controlled, while the dependent variable is the one that is measured or observed.

Front

How can you determine the speed of an object from a distance vs. time graph?

Back

The speed can be determined by calculating the slope of the line on the graph, which represents distance over time.

Front

What is unbalanced force and how does it affect motion?

Back

Unbalanced forces result in a net force that causes an object to accelerate in the direction of the greater force.
