Force and Motion STAAR Review

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces that are in contact. More friction occurs when an object rubs against a rough surface.

Front

Why is it important to conduct multiple trials in an experiment?

Back

Conducting multiple trials makes the results more reliable by reducing the impact of errors or anomalies.

Front

What force pulls objects down towards the Earth?

Back

Gravity is the force that pulls objects down towards the Earth.

Front

What should be done to ensure a fair experiment when testing different ramps?

Back

The same car should be used on all ramps to ensure a fair comparison.

Front

Which box will move the farthest when equal force is applied?

Back

The box with the least resistance or friction will move the farthest.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects towards the center of the Earth, affecting their motion.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces, making it harder for objects to slide.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, indicating how much motion it has.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
