Forces and Motion

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate or change its motion. They occur when the net force acting on an object is not zero.

Front

What is weight?

Back

Weight is the force exerted on an object due to gravity, which depends on the mass of the object and the acceleration due to gravity.

Front

How do you calculate mass using force and acceleration?

Back

Mass can be calculated using Newton's second law: Mass = Force / Acceleration.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and causing them to fall towards the Earth.

Front

What happens when two objects of the same shape are dropped from the same height?

Back

Both objects will hit the ground at the same time, regardless of their mass, if air resistance is negligible.

Front

What are balanced forces?

Back

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

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

How does mass affect weight?

Back

Weight increases with mass; the more mass an object has, the greater the gravitational force acting on it.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
