Front

What is the effect of mass on the speed of an object in motion?

Back

The speed of an object can change based on its mass; generally, a decrease in mass can lead to an increase in speed when the same amount of force is applied.

Front

What force is responsible for pulling objects towards the Earth?

Back

Gravity is the force that pulls objects towards the Earth.

Front

How does mass affect the distance an object can move when the same force is applied?

Back

An object with less mass will move farther than an object with more mass when the same amount of force is applied.

Front

What happens to an object when it is acted upon by gravity while on an inclined surface?

Back

The object will accelerate down the incline due to the force of gravity acting on it.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact; it can slow down or stop the movement of an object.

Front

How does increasing friction between a skateboard and a rider's foot affect their ability to perform tricks?

Back

Increasing friction helps the rider maintain better control and stability, reducing the likelihood of slipping off the skateboard.

Front

What is the relationship between force, mass, and acceleration as described by Newton's second law of motion?

Back

Newton's second law states that force equals mass times acceleration (F=ma), meaning that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the role of gravity in sports like basketball?

Back

Gravity affects the trajectory of the basketball, pulling it down towards the ground after it has been thrown.

Front

How does the mass of an object influence its inertia?

Back

Inertia is the resistance of an object to change its state of motion; greater mass means greater inertia, making it harder to start or stop the object's motion.

Front

What is the principle of conservation of energy in the context of motion?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed; in motion, potential energy can convert to kinetic energy and vice versa.
