As force increases, acceleration:

Front

increases

Back

What affects an object's acceleration?

Front

It's mass and the net force: The bigger the mass the lower the acceleration. The bigger the net force the greater the acceleration.

Back

Describe the possible motion of an object with a net force acting on it.

Front

It is accelerating: speeding up, slowing down, or turning

Back

-32 m/s/s

Front

What is the acceleration of the object shown?

Back

Equation for Newton's 2nd Law

Front

F=ma

Back

Which object would accelerate the fastest if the same force was applied: 1 kg, 4 kg, 6 kg, 10 kg

Front

1 kg: As mass decreases, acceleration increases

Back

How much does 1 kg weigh?

Front

10 N

Back

What is the weight of a 50 kg mass?

Front

(1 kg=10 N) 500 N

Back

As mass increases, acceleration

Front

decreases

Back

A 35 N force would acceleration a 7 kg mass at:

Front

5 m/s/s

Back

Which force would produce the greatest acceleration on a 5 kg mass: 1 N, 4 N, 6 N, 10 N

Front

10 N: As force increases, acceleration increases

Back

If the object is at rest, it will stay at rest. If the object was moving, it will continue to move at a constant velocity

Front

Describe the possible motion(s):

Back

What does equilibrium mean?

Front

net force = 0 or balanced forces

Back

Describe the forces acting on an object with a net force=0

Front

balanced

Back

An object will accelerate in what direction?

Front

The direction of the net force

Back

-8 N

Front

What is the net force for the object shown?

Back

Describe the possible motions of an object with a net force = 0

Front

at rest or moving at a constant velocity

Back

What is the weight of a 2 kg mass?

Front

(1kg= 10 N) 20 N

Back

What mass would a 50 N force accelerate at 25 m/s/s?

Front

2 kg

Back

A 10 kg mass producing a 2 m/s/s acceleration would require what net force?

Front

20 N
