5.6D & 3.6B Force and Experimental Design

Front

What is the force that opposes the motion of an object?

Back

Frictional force.

Front

What is the effect of friction on the movement of an object?

Back

It slows down movement.

Front

What is the term for the resistance encountered when two surfaces slide against each other?

Back

Friction.

Front

What is a testable prediction in an experiment?

Back

Hypothesis.

Front

What is the downward force that pulls objects toward the Earth?

Back

Gravity.

Front

What are the two main types of friction?

Back

Static friction and kinetic friction.

Front

How does surface texture affect friction?

Back

Rough surfaces increase friction, while smooth surfaces decrease it.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with mass.

Front

What is the formula for calculating gravitational force?

Back

F = m * g, where F is the force, m is mass, and g is the acceleration due to gravity.

Front

What is the role of a hypothesis in experimental design?

Back

It provides a basis for testing and experimentation.
