5th Grade Cycle 2 Assessment Review

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact. It acts against a push or pull and slows down an object.

Front

How does the surface affect friction?

Back

The amount of friction can vary depending on the texture and material of the surfaces in contact. Rough surfaces create more friction than smooth surfaces.

Front

What is the best way to test friction?

Back

To test friction, roll three toy cars on three different surfaces from the same starting point and apply the same force.

Front

What happens to the force needed to pull an object on a ramp if more weight is added?

Back

If more weight is added below the ramp, more force will be needed to pull the object.

Front

What causes a moving object to stop?

Back

A moving object stops due to the force of friction acting in the opposite direction of its motion.

Front

What would happen to the seasons if the Earth was not tilted on its axis?

Back

If the Earth was not tilted, there would be no change of seasons during the year.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting how they move and stop.

Front

What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply force in a more effective way, such as levers, pulleys, and ramps.

Front

What is the relationship between force and motion?

Back

Force is needed to change the motion of an object. An object at rest will stay at rest unless acted upon by a force.

Front

What is an example of a push force?

Back

Pushing a toy car forward is an example of a push force.
