5.3 Force and Motion

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an apple on the edge of a table has potential energy.

Front

What is net force?

Back

Net force is the total combination of all forces acting on an object. It determines the object's motion.

Front

What is a force?

Back

A force is a push or pull acting on an object. Forces can cause an object to start moving, stop moving, or change direction.

Front

What is speed?

Back

Speed is the distance an object travels in a specific amount of time. It is how fast something is moving.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what keeps us on the ground and causes objects to fall.

Front

What is motion?

Back

Motion is the change in position of an object over time. If an object is moving, it is in motion.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction. They do not cause a change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.
