Force, Motion, and Energy

Front

What is the importance of repeating an experiment multiple times?

Back

Repeating an experiment multiple times helps to ensure reliable results and reduces the impact of random errors.

Front

What tools are commonly used to measure the effect of friction on an object?

Back

Measuring tape and stopwatch are commonly used to measure the effect of friction.

Front

What force is observed when a copper wire is wrapped around an iron nail and connected to a battery?

Back

The force of magnetism is observed when the nail attracts small nails and paper clips.

Front

Why is it important to test only one variable in an experiment?

Back

Testing only one variable allows for clear identification of what caused any changes in the results.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object and can slow it down or stop it.

Front

Define force in the context of physics.

Back

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

Front

What is motion in physics?

Back

Motion is the change in position of an object over time.

Front

Explain the concept of energy in relation to motion.

Back

Energy is the capacity to do work, and in relation to motion, it is the energy an object possesses due to its movement (kinetic energy) or its position (potential energy).

Front

What is the role of a control in an experiment?

Back

A control is used as a standard for comparison to ensure that the results of the experiment are due to the variable being tested.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
