STEMSCOPES - Force and Motion

Front

What is kinetic energy?

Back

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

Front

Which marble has more kinetic energy, ceramic or steel?

Back

Steel has more kinetic energy than ceramic when both are moving at the same speed.

Front

What is gravity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve increasing speed, decreasing speed, or changing direction.

Front

What causes a change in motion?

Back

A change in motion is caused by unbalanced forces acting on an object.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change speed.

Front

What happens to a book sitting at rest on a chair?

Back

The book experiences balanced forces; the force of gravity pulling it down is balanced by the normal force from the chair pushing it up.

Front

What is motion?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.
