If two objects are under the influence of equal forces, they have the same acceleration.
1. True False During the collision of a locomotive with a car, the car exerts an equal size force on the locomotive as the locomotive exerts on the car.
2. True False The net force which acts on an object which maintains a constant velocity is zero.
3. True False An object's velocity will change if a net force acts on the object.
4. True False If a net force acts on an object, the object's speed will change.
5. True False A bicycle initially moving at a constant velocity will slow down unless a small net force is applied.

Explanation:

If two objects are under the influence of equal forces, they have the same acceleration  - False .

If their mass differs , their acceleration will also change.

1 )During the collision of a locomotive with a car, the car exerts an equal size force on the locomotive as the locomotive exerts on the car

True because action and reaction forces are equal.

2. True False The net force which acts on an object which maintains a constant velocity is zero

True , because if acceleration is zero , net force will be zero.

3. True False An object's velocity will change if a net force acts on the object.

True , because , if there is acceleration , there is force.

True False A bicycle initially moving at a constant velocity will slow down unless a small net force is applied

False , A bicycle initially moving at a constant velocity will  not slow down

unless a small net force is applied .

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
