Newton's Second Law of Motion F=ma) _ GCSE Physics

The video explains how an object accelerates in the direction of the resultant force, with greater forces causing greater acceleration. It discusses the inverse relationship between mass and acceleration, and introduces the equation F=ma. A practical example is provided, and it concludes with a fun fact about the unit of force, the newton.

What happens to the acceleration of an object if the force applied to it is doubled?

• The acceleration is halved.

• The acceleration remains the same.

• The acceleration is doubled.

• The acceleration is tripled.

If the mass of an object is doubled, what happens to its acceleration for the same force?

• The acceleration is tripled.

• The acceleration remains the same.

• The acceleration is halved.

• The acceleration is doubled.

Which equation represents the relationship between force, mass, and acceleration?

• F = a / m

• F = m + a

• F = m / a

• F = m * a

A car with a mass of 700 kg is pushed with an acceleration of 0.05 m/s². What is the force applied?

• 350 N

• 0.035 N

• 70 N

• 35 N

What is approximately the weight of an apple in terms of force?

• 1 newton

• 10 newtons

• 0.1 newton

• 5 newtons
