Net force and energy 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 does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when they are not equal, causing a change in motion of the object.

Front

What is gravity?

Back

Gravity is a non-contact force that pulls objects toward each other, affected by their mass and the distance between them.

Front

What is magnetism?

Back

Magnetism is a non-contact force that can either push or pull objects, depending on their orientation, strength, and magnitude.

Front

What determines the amount of potential energy an object has?

Back

The amount of potential energy is determined by how high the object is off the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and speed.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is friction?

Back

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

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with greater mass and decreases with greater distance.
