Forces

Front

What is the force that causes a compass needle to move?

Back

Magnetism is the force that causes a compass needle to align with the Earth's magnetic field.

Front

What type of force is present when all forces acting on an object are equal and opposite?

Back

A balanced force is present when all forces acting on an object are equal and opposite, resulting in no change in motion.

Front

True or False: As the mass of an object increases, the force needed to move it decreases.

Back

False. As the mass of an object increases, more force is needed to move it.

Front

What happens to the motion of an object if more mass is added while applying the same force?

Back

The motion will decrease because more mass requires more force to achieve the same acceleration.

Front

What type of force is applied when pushing an object away from you?

Back

A push is the type of force applied when you exert force to move an object away from you.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate.

Front

How does mass affect the force needed to move an object?

Back

The greater the mass of an object, the more force is required to move it.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).
