Force & Net Force

Front

What is a balanced force?

Back

A balanced force is a situation where two or more forces acting on an object are equal in size but opposite in direction, resulting in no change in the object's motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

What happens to an object when the net force acting on it is zero?

Back

When the net force acting on an object is zero, the object remains at rest or continues to move at a constant velocity.

Front

How is kinetic energy related to the motion of an object?

Back

Kinetic energy is the energy an object possesses due to its motion, which increases with the speed of the object.

Front

What is the formula for calculating net force?

Back

Net force is calculated by subtracting opposing forces from each other: Net Force = Force applied - Force opposing.

Front

In a tug-of-war, how do you determine which team wins?

Back

The team that exerts a greater net force on the rope will win, causing the ribbon in the middle to move towards them.

Front

What is the significance of point X in a roller coaster's track?

Back

Point X is where the roller coaster car has the greatest kinetic energy, typically at the lowest point of the track due to gravitational potential energy converting to kinetic energy.

Front

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

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted on that mass by gravity (Weight = mass x gravitational acceleration).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.
