Force in one dimension

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a)

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

How do you calculate the weight of an object?

Back

Weight (W) = mass (m) × gravitational acceleration (g), where g ≈ 9.81 m/s².

Front

What is tension in a rope?

Back

Tension is the force exerted along the length of a rope or string when it is pulled tight.

Front

What is the relationship between mass and weight?

Back

Weight is the force due to gravity acting on an object's mass.

Front

If a 60 kg cart accelerates at 2.0 m/s², what is the force applied?

Back

Force = 60 kg × 2.0 m/s² = 120 N.

Front

What happens to the apparent weight of an object in an accelerating elevator?

Back

The apparent weight increases if the elevator accelerates upward and decreases if it accelerates downward.

Front

In a collision, how do forces compare between two colliding objects?

Back

According to Newton's Third Law, the forces are equal in magnitude and opposite in direction.

Front

What is the significance of the net force acting on an object?

Back

The net force determines the object's acceleration according to Newton's Second Law.

Front

How do you find the mass of an object if you know its weight?

Back

Mass = Weight / gravitational acceleration (g).
