Gravity and Friction Test Review

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the unit of force?

Back

The unit of force is Newton (N).

Front

What does it mean if the net force is 0 N?

Back

If the net force is 0 N, it means that all the forces acting on an object are balanced, and the object will not accelerate.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

How does mass affect the force of gravity?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is an example of a balanced force?

Back

An example of a balanced force is when two people push a box with equal force in opposite directions, resulting in no movement.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when one person pushes a box harder than another person pulls it, causing the box to move.

Front

What is the effect of friction on motion?

Back

Friction slows down or stops the motion of an object.
