Force and Motion

Front

What happens if the second hill of a rollercoaster is taller than the first?

Back

The rollercoaster would not make it up over the second hill due to insufficient energy.

Front

Why don't skateboarders keep flying through the air when they launch off a ramp?

Back

The force of gravity works against the skateboarder's inertia, pulling them back down.

Front

What is the definition of force?

Back

A force is a push or a pull upon an object resulting from the object's interaction with another object.

Front

What causes a rolling ball to stop?

Back

Friction is the force that causes a rolling ball to stop.

Front

What type of energy does a stretched rubber band possess?

Back

A stretched rubber band has potential energy.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does gravity affect objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion and trajectory.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the relationship between mass and force according to Newton's second law?

Back

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

Front

What role does friction play in motion?

Back

Friction opposes motion between two surfaces in contact, slowing down or stopping moving objects.
