GKE Inv 2 F=ma & gravity

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = M x A.

Front

What is the formula to calculate force?

Back

F = M x A, where F is force, M is mass, and A is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the unit of mass?

Back

The unit of mass is the kilogram (kg).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

If a force of 10 N is applied to a mass of 2 kg, what is the acceleration?

Back

A = F / M = 10 N / 2 kg = 5 m/s².

Front

What does it mean if an object is in free fall?

Back

An object in free fall is only under the influence of gravity, with no other forces acting on it.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you calculate the mass of an object if you know the force applied and the acceleration?

Back

Mass can be calculated using the formula M = F / A.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object and is calculated as Weight = Mass x Gravity (W = M x g).
