Calculations Newton's 2nd law

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd 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 * a.

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

How do you calculate mass using Newton's 2nd Law?

Back

Mass can be calculated using the formula m = F / a, where F is the net force and a is the acceleration.

Front

If a net force of 400 N is applied to a motorcycle and it accelerates at 4 m/s², what is the mass of the motorcycle?

Back

100 kg.

Front

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

Back

The unit of force is the Newton (N).

Front

How do you calculate acceleration using Newton's 2nd Law?

Back

Acceleration can be calculated using the formula a = F / m, where F is the net force and m is the mass.

Front

If a truck with a mass of 1,000 kg stops in 0.5 seconds after hitting a wall, how do you find the force exerted during the collision?

Back

Use the formula F = m * a. First, calculate the deceleration (a) and then apply the formula.

Front

What is the relationship between mass, acceleration, and force?

Back

The relationship is that force is the product of mass and acceleration (F = m * a). Increasing mass or acceleration increases the force.

Front

What is the net force acting on an object?

Back

The net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

If an object with a mass of 5.0 kg accelerates at 8.0 m/s², what is the force applied?

Back

40 N.
