Units
The unit is kg
mass
A toy car with a mass of 0.5 kg accelerates at 2 m/s^2. Calculate the force acting on the car.
1N
A force of 12 N acts on an object, causing it to accelerate at 3 m/s^2. Find the mass of the object.
4kg
A force of 80 N acts on an object with a mass of 10 kg. What is the acceleration of the object?
8 m/s2
What is newton's first law?
Law of Inertia
An object at rest stays at rest, or an object in motion stays in motion unless acted on by an unbalanced force.
The unit is m/s^2
acceleration
A baseball with a mass of 0.145 kg is hit by a bat, causing it to accelerate at 35 m/s^2. What force was applied to the baseball?
5.075 N
A rocket engine produces a thrust force of 45,000 N during liftoff. If the rocket accelerates at 25 m/s^2, what is its mass?
1,800 kg
A rocket with a mass of 25,000 kg experiences a thrust force of 1,000,000 N during liftoff. Calculate the initial acceleration of the rocket.
40 m/s2
