5.6D Force and Motion

Front

What is the definition of force in physics?

Back

Force is a vector quantity that represents an interaction that causes an object to change its velocity, direction, or shape. It is measured in Newtons (N).

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, and it is responsible for the downward motion of objects towards the Earth.

Front

How does mass affect the force required to accelerate an object?

Back

The greater the mass of an object, the more force is required to achieve the same acceleration, according to Newton's second law of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in Newtons (N).

Front

What is the concept of net force?

Back

Net force is the total force acting on an object when all the individual forces acting on it are combined. It determines the object's acceleration.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the relationship between force and acceleration?

Back

Force and acceleration are directly proportional; as the force acting on an object increases, the acceleration of that object also increases, provided the mass remains constant.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes the relative motion of two surfaces in contact. It can slow down or stop the motion of an object.

Front

What are the different types of forces?

Back

The different types of forces include gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.
