Newton's Second Law of Acceleration

Jenny applies a 60 N force to a 20 Kg cart, what is the acceleration of the cart if friction can be neglected?

• 1200 m/s/s

• 0.33 m/s/s

• 20 m/s/s

• 3 m/s/s

According to __________, the acceleration of an object is equal to the net force acting on the object divided by the object's mass. 

• Newton's Second Law

• Newton's Third Law

• Newton's First Law

If you increase the force on an object, its acceleration (a)  

• also increases

• decreases

• stays the same

• stops

A 20 kg bike accelerates at 10 m/s².  What was the force?

• 25 Newtons

• 20 Newtons

• 200 Newtons

• 10 Newtons

A 10-kg crate is pushed across a frictionless surface with a force of 30 N. What is its acceleration?

• 300 m/s²

• 3 m/s²

• 20 m/s²

• 0.33 m/s²

What is Newtons 2nd law of motion?

• Pancakes 

• Force= Mass multiplied by acceleration

• For every action there is a equal and opposite  re-action.

• Law of gravity 

The force needed to accelerate a 500 kg object at a rate of 50 m/s² is ​ (a)   .

• 10 N
• 25 m/s2
• 25,000 N

Provide an example of Newton's 2nd Law

Force is equal to

(a)   * ​ (b)  

• mass

• acceleration

• weight

• speed
