A man pushes a 1,000 kg car at an acceleration of 0.05 m/s/s.
Newton's second law says that the force equals the mass of the object times it's acceleration.
F = ma
The mass of the car, 1,000 kg, times the acceleration of the car, 0.05 m/s/s, equals 50.
The force that the man exerts on the car is 50 newtons.
50 = (1,000)(0.05)
Example:
5,000 newtons is exerted on a car with a mass of 2,000kg. What is the acceleration of the car?
F = ma
5,000 = 2,000 * a
a = 2.5 m/s/s
The car has an acceleration of 2.5 ms/s/s.
Newton's second law
Explain:
A man pushes a 1,000 kg car at an acceleration of 0.05 m/s/s.
Newton's second law says that the force equals the mass of the object times it's acceleration.
F = ma
The mass of the car, 1,000 kg, times the acceleration of the car, 0.05 m/s/s, equals 50.
The force that the man exerts on the car is 50 newtons.
50 = (1,000)(0.05)
Example:
5,000 newtons is exerted on a car with a mass of 2,000kg. What is the acceleration of the car?F = ma
5,000 = 2,000 * a
a = 2.5 m/s/s
The car has an acceleration of 2.5 ms/s/s.
Equation:
F = forcem = mass
a = acceleration
F = m*a
